Open and Save in Spreadsheet control
18 Jul 202424 minutes to read
To import an excel file, it needs to be read and converted to client side Spreadsheet model. The converted client side Spreadsheet model is sent as JSON which is used to render Spreadsheet. Similarly, when you save the Spreadsheet, the client Spreadsheet model is sent to the server as JSON for processing and saved. Server configuration is used for this process.
Open
The Spreadsheet component opens an Excel document with its data, style, format, and more. To enable this feature, set allowOpen as true and assign service url to the openUrl property.
User Interface:
In user interface you can open an Excel document by clicking File > Open menu item in ribbon.
The following sample shows the Open option by using the openUrl property in the Spreadsheet control. You can also use the beforeOpen event to trigger before opening an Excel file.
<ejs-spreadsheet id="spreadsheet" openUrl="Open" allowOpen = "true" beforeOpen="beforeOpen">
</ejs-spreadsheet>
<script>
function beforeOpen(args) {
// your code snippets here
}
</script>public IActionResult Open(IFormCollection openRequest)
{
OpenRequest open = new OpenRequest();
open.File = openRequest.Files[0];
return Content(Workbook.Open(open));
}Find the below table for the beforeOpen event arguments.
| Parameter | Type | Description |
|---|---|---|
| file | FileList or string or File | To get the file stream. FileList - contains length and item index. File - specifies the file lastModified and file name. |
| cancel | boolean | To prevent the open operation. |
| requestData | object | To provide the Form data. |
NOTE
Open an excel file using a file uploader
If you explore your machine to select and upload an excel document using the file uploader, you will receive the uploaded document as a raw file in the success event of the file uploader. In this success event, you should pass the received raw file as an argument to the Spreadsheet’s open method to see the appropriate output.
The following code example shows how to import an excel document using file uploader in spreadsheet.
@using Syncfusion.EJ2
@{
var asyncSettings = new Syncfusion.EJ2.Inputs.UploaderAsyncSettings { SaveUrl = @Url.Content("Home/Save"), RemoveUrl = @Url.Content("Home/Remove") };
}
<ejs-spreadsheet id="spreadsheet" openUrl="Home/Open">
</ejs-spreadsheet>
<ejs-uploader id="UploadFiles" success="onSuccess" asyncSettings="@asyncSettings" allowedExtensions=".xls, .xlsx, .csv">
</ejs-uploader>
<script>
function onSuccess(args){
var ssObj = ej.base.getComponent(document.getElementById('spreadsheet'), 'spreadsheet');
if (args.operation === 'upload')
ssObj.open({ file: args.file.rawFile });
}
</script>public IActionResult Open(IFormCollection openRequest)
{
OpenRequest open = new OpenRequest();
open.File = openRequest.Files[0];
return Content(Workbook.Open(open));
}
public void Save(IList<IFormFile> UploadFiles)
{
long size = 0;
try
{
foreach (var file in UploadFiles)
{
var filename = ContentDispositionHeaderValue
.Parse(file.ContentDisposition)
.FileName
.Trim('"');
filename = hostingEnv.WebRootPath + $@"\{filename}";
size += file.Length;
if (!System.IO.File.Exists(filename))
{
using (FileStream fs = System.IO.File.Create(filename))
{
//file.CopyTo(fs);
//fs.Flush();
}
}
else
{
using (FileStream fs = System.IO.File.Open(filename, FileMode.Append))
{
//file.CopyTo(fs);
//fs.Flush();
}
}
}
}
catch (Exception e)
{

Response.StatusCode = 204;
Response.HttpContext.Features.Get<IHttpResponseFeature>().ReasonPhrase = "File failed to upload";
Response.HttpContext.Features.Get<IHttpResponseFeature>().ReasonPhrase = e.Message;
}
}

}Open an external URL excel file while initial load
You can achieve to access the remote excel file by using the created event. In this event you can fetch the excel file and convert it to a blob. Convert this blob to a file and open this file by using Spreadsheet component open method.
<ejs-spreadsheet id="spreadsheet" openUrl="Open" allowOpen ="true" created="created">
</ejs-spreadsheet>
<script>
function created() {
var spreadsheet = ej.base.getComponent(document.getElementById('spreadsheet'), 'spreadsheet');
fetch("https://cdn.syncfusion.com/scripts/spreadsheet/Sample.xlsx") // fetch the remote url
.then((response) => {
response.blob().then((fileBlob) => { // convert the excel file to blob
var file = new File([fileBlob], "Sample.xlsx"); //convert the blob into file
spreadsheet.open({ file: file }); // open the file into Spreadsheet
})
})
}
</script>public IActionResult Open(IFormCollection openRequest)
{
OpenRequest open = new OpenRequest();
open.File = openRequest.Files[0];
return Content(Workbook.Open(open));
}Open an excel file from blob data
By default, the Spreadsheet control provides an option to browse files from the local file system and open them within the control. If you want to open an Excel file from blob data, you need to fetch the blob data from the server or another source and convert this blob data into a File object. Then, you can use the open method in the Spreadsheet control to load that File object.
Please find the code to fetch the blob data and load it into the Spreadsheet control below.
<ejs-spreadsheet id="spreadsheet" openUrl="Home/Open" saveUrl="Home/Save" created="created">

}Open an Excel file located on a server
By default, the Spreadsheet control provides an option to browse files from the local file system and open them within the control. If you want to load an Excel file located on a server, you need to configure the server endpoint to fetch the Excel file from the server location, process it using Syncfusion.EJ2.Spreadsheet.AspNet.Core, and send it back to the client side as JSON data. On the client side, you should use the openFromJson method to load that JSON data into the Spreadsheet control.
public IActionResult Open([FromBody] FileOptions options)
{
OpenRequest open = new OpenRequest();
string filePath = _env.ContentRootPath.ToString() + "\\Files\\" + options.FileName + ".xlsx";
// Getting the file stream from the file path.
FileStream fileStream = new FileStream(filePath, FileMode.Open);
// Converting "MemoryStream" to "IFormFile".
IFormFile formFile = new FormFile(fileStream, 0, fileStream.Length, "", options.FileName + ".xlsx");
open.File = formFile;
// Processing the Excel file and return the workbook JSON.
var result = Workbook.Open(open);
fileStream.Close();
return Content(result);
}
public class FileOptions
{
public string FileName { get; set; } = string.Empty;
} // Fetch call to server to load the Excel file.
fetch('Home/Open', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({ FileName: 'Sample' }),
})
.then((response) => response.json())
.then((data) => {
// Load the JSON data into spreadsheet.
spreadsheet.openFromJson({ file: data });
})You can find the server endpoint code to fetch and process the Excel file in this attachment.
Open an excel file using a hosted web service in AWS Lambda
Before proceeding with the opening process, you should deploy the spreadsheet open/save web API service in AWS Lambda. To host the open/save web service in the AWS Lambda environment, please refer to the following KB documentation.
After deployment, you will get the AWS service URL for the open and save actions. Before opening the Excel file with this hosted open URL, you need to prevent the default file opening process to avoid getting a corrupted file on the open service end. The spreadsheet component appends the file to the formData and sends it to the open service, which causes the file to get corrupted. To prevent this, set the args.cancel value to true in the beforeOpen event. After that, you will get the selected file in the beforeOpen event argument. Then, convert this file into a base64 string and send it to the open service URL using a fetch request.
On the open service end, convert the base64 string back to a file and pass it as an argument to the workbook Open method. The open service will process the file and return the spreadsheet data in JSON format. You will then receive this JSON data in the fetch success callback. Finally, use the openFromJson method to load this JSON data into the spreadsheet component.
The following code example shows how to open an Excel file using a hosted web service in AWS Lambda, as mentioned above.
<ejs-spreadsheet id="spreadsheet" openUrl="https://xxxxxxxxxxxxxxxxxx.amazonaws.com/Prod/api/spreadsheet/open" allowOpen = "true" beforeOpen="beforeOpen">

var spreadsheet = ej.base.getComponent(document.getElementById('spreadsheet'), 'spreadsheet');
eventArgs.cancel = true; // To prevent the default open action.
if (eventArgs.file) {
const reader = new FileReader();
reader.readAsDataURL(eventArgs.file);
reader.onload = () => {
// Removing the xlsx file content-type.
const base64Data = reader.result.replace('data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,', '');
openExcel({
file: base64Data,
extension: eventArgs.file.name.slice(eventArgs.file.name.lastIndexOf('.') + 1),

</script>Open an excel file from Base64 string data
In the Syncfusion Spreadsheet component, there is no direct option to open data as a Base64 string. To achieve this, the import() function fetches the Base64 string, converts it to a Blob, creates a File object from the Blob, and then opens it using the open method in the spreadsheet.
The following code example shows how to open the spreadsheet data as base64 string.

}Open excel file into a read-only mode
You can open excel file into a read-only mode by using the openComplete event. In this event, you must protect all the sheets and lock its used range cells by using protectSheet and lockCells methods.
<ejs-spreadsheet id="spreadsheet" openComplete="openComplete" openUrl="Home/Open">
</ejs-spreadsheet>
<script>
function openComplete(args) {
var spreadsheet = ej.base.getComponent(document.getElementById('spreadsheet'), 'spreadsheet');
var sheets = spreadsheet.sheets;
for (var index = 0; index < sheets.length; index++) {
var name = spreadsheet.sheets[index].name;
var protectSetting = {
selectCells: true,
formatCells: false,
};
//To protect the sheet using sheet name
spreadsheet.protectSheet(name, protectSetting);
var address = ejs.spreadsheet.getRangeAddress([
0,
0,
sheets[index].usedRange.rowIndex,
sheets[index].usedRange.colIndex,
]);
//To lock the used range cells
spreadsheet.lockCells(name + '!' + address, true);
}
}
</script>public IActionResult Open(IFormCollection openRequest)
{
OpenRequest open = new OpenRequest();
open.File = openRequest.Files[0];
return Content(Workbook.Open(open));
}Configure JSON deserialization options
Previously, when opening a workbook JSON object into the Spreadsheet using the openFromJson method, the entire workbook, including all features specified in the JSON object, was processed and loaded into the Spreadsheet.
Now, you have the option to selectively ignore some features during the opening of the JSON object by configuring deserialization options and passing them as arguments to the openFromJson method. This argument is optional, and if not configured, the entire workbook JSON object will be loaded without ignoring any features.
spreadsheet.openFromJson({ file: file }, { ignoreStyle: true });| Options | Description |
|---|---|
| onlyValues | If true, only the cell values will be loaded. |
| ignoreStyle | If true, styles will be excluded when loading the JSON data. |
| ignoreFormula | If true, formulas will be excluded when loading the JSON data. |
| ignoreFormat | If true, number formats will be excluded when loading the JSON data. |
| ignoreConditionalFormat | If true, conditional formatting will be excluded when loading the JSON data. |
| ignoreValidation | If true, data validation rules will be excluded when loading the JSON data. |
| ignoreFreezePane | If true, freeze panes will be excluded when loading the JSON data. |
| ignoreWrap | If true, text wrapping settings will be excluded when loading the JSON data. |
| ignoreChart | If true, charts will be excluded when loading the JSON data. |
| ignoreImage | If true, images will be excluded when loading the JSON data. |
| ignoreNote | If true, notes will be excluded when loading the JSON data. |
The following code snippet demonstrates how to configure the deserialization options and pass them as arguments to the openFromJson method:
@using Syncfusion.EJ2

}Add custom header during open
You can add your own custom header to the open action in the Spreadsheet. For processing the data, it has to be sent from server to client side and adding customer header can provide privacy to the data with the help of Authorization Token. Through the beforeOpen event, the custom header can be added to the request during open action.
<ejs-spreadsheet id="spreadsheet" beforeOpen="beforeOpen" openUrl="Home/Open">
</ejs-spreadsheet>
<script>
function beforeOpen(args) {
args.requestData["headers"] = {
...args.requestData,
headers: { Authorization: "YOUR TEXT" }
};
}
</script>public IActionResult Open(IFormCollection openRequest)
{
OpenRequest open = new OpenRequest();
open.File = openRequest.Files[0];
return Content(Workbook.Open(open));
}External workbook confirmation dialog
When you open an excel file that contains external workbook references, you will see a confirmation dialog. This dialog allows you to either continue with the file opening or cancel the operation. This confirmation dialog will appear only if you set the AllowExternalWorkbook property value to false during the open request, as shown below. This prevents the spreadsheet from displaying inconsistent data.
public IActionResult Open(IFormCollection openRequest)
{
OpenRequest open = new OpenRequest();
open.AllowExternalWorkbook = false;
open.File = openRequest.Files[0];
return Content(Workbook.Open(open));
}This feature is only applicable when importing an Excel file and not when loading JSON data or binding cell data.
Supported file formats
The following list of Excel file formats are supported in Spreadsheet:
- Microsoft Excel (.xlsx)
- Microsoft Excel 97-2003 (.xls)
- Comma Separated Values (.csv)
- Excel Macro-Enabled Workbook (.xlsm)
- Excel Binary Workbook(.xlsb)
Save
The Spreadsheet component saves its data, style, format, and more as Excel file document. To enable this feature, set allowSave as true and assign service url to the saveUrl property.
User Interface:
In user interface, you can save Spreadsheet data as Excel document by clicking File > Save As menu item in ribbon.
The following sample shows the Save option by using the saveUrl property in the Spreadsheet control. You can also use the beforeSave event to trigger before saving the Spreadsheet as an Excel file.
<ejs-spreadsheet id="spreadsheet" saveUrl="Save" allowSave = "true">
</ejs-spreadsheet>public void Save(SaveSettings saveSettings)
{
Workbook.Save(saveSettings);
}Find the below table for the beforeSave event arguments.
| Parameter | Type | Description |
|---|---|---|
| url | string | Specifies the save url. |
| fileName | string | Specifies the file name. |
| saveType | SaveType | Specifies the saveType like Xlsx, Xls, Csv and Pdf. |
| customParams | object | Passing the custom parameters from client to server while performing save operation. |
| isFullPost | boolean | It sends the form data from client to server, when set to true. It fetches the data from client to server and returns the data from server to client, when set to false. |
| needBlobData | boolean | You can get the blob data if set to true. |
| cancel | boolean | To prevent the save operations. |
NOTE
Save an excel file as blob data
By default, the Spreadsheet control saves the Excel file and downloads it to the local file system. If you want to save an Excel file as blob data, you need to set needBlobData property to true and isFullPost property to false in the beforeSave event of the spreadsheet. Subsequently, you will receive the spreadsheet data as a blob in the saveComplete event. You can then post the blob data to the server endpoint for saving.
Please find below the code to retrieve blob data from the Spreadsheet control below.

}Save an Excel file to a server
By default, the Spreadsheet control saves the Excel file and downloads it to the local file system. If you want to save an Excel file to a server location, you need to configure the server endpoint to convert the spreadsheet data into a file stream and save it to the server location. To do this, first, on the client side, you must convert the spreadsheet data into JSON format using the saveAsJson method and send it to the server endpoint. On the server endpoint, you should convert the received spreadsheet JSON data into a file stream using Syncfusion.EJ2.Spreadsheet.AspNet.Core, then convert the stream into an Excel file, and finally save it to the server location.
// Convert the spreadsheet workbook to JSON data.
spreadsheet.saveAsJson().then((json) => {
const formData = new FormData();
formData.append('FileName', "Sample");
formData.append('saveType', 'Xlsx');
// Passing the JSON data to perform the save operation.
formData.append('JSONData', JSON.stringify(json.jsonObject.Workbook));
formData.append('PdfLayoutSettings', JSON.stringify({ FitSheetOnOnePage: false }));
// Using fetch to invoke the save process.
fetch('Home/Save', {
method: 'POST',
body: formData
}).then((response) => {
console.log(response);
});
}); public string Save(SaveSettings saveSettings)
{
ExcelEngine excelEngine = new ExcelEngine();
IApplication application = excelEngine.Excel;
try
{
// Save the workbook as stream.
Stream fileStream = Workbook.Save<Stream>(saveSettings);
// Using XLSIO, we are opening the file stream and saving the file in the server under "Files" folder.
// You can also save the stream file in your server location.
IWorkbook workbook = application.Workbooks.Open(fileStream);
string basePath = _env.ContentRootPath + "\\Files\\" + saveSettings.FileName + ".xlsx";
var file = System.IO.File.Create(basePath);
fileStream.Seek(0, SeekOrigin.Begin);
// To convert the stream to file options.
fileStream.CopyTo(file);
file.Dispose();
fileStream.Dispose();
return string.Empty;
}
catch (Exception ex)
{
return ex.Message;
}
}You can find the server endpoint code to save the spreadsheet data as an Excel file in this attachment.
Save an excel file using a hosted web service in AWS Lambda
Before proceeding with the save process, you should deploy the spreadsheet open/save web API service in AWS Lambda. To host the open/save web service in the AWS Lambda environment, please refer to the following KB documentation.
After deployment, you will get the AWS service URL for the open and save actions. Before saving the Excel file with this hosted save URL, you need to prevent the default save action to avoid getting a corrupted excel file on the client end. The save service returns the file stream as a result to the client, which can cause the file to become corrupted. To prevent this, set the args.cancel value to true in the beforeSave event. After that, convert the spreadsheet data into JSON format using the saveAsJson method in the beforeSave event and send it to the save service endpoint URL using a fetch request.
On the server side, the save service will take the received JSON data, pass it to the workbook Save method, and return the result as a base64 string. The fetch success callback will receive the Excel file in base64 string format on the client side. Finally, you can then convert the base64 string back to a file on the client end to obtain a non-corrupted Excel file.
The following code example shows how to save an Excel file using a hosted web service in AWS Lambda, as mentioned above.
<ejs-spreadsheet id="spreadsheet" saveUrl="https://xxxxxxxxxxxxxxxxxxxxxxxxx.amazonaws.com/Prod/api/spreadsheet/save" allowSave="true" beforeSave="beforeSave">
</ejs-spreadsheet>
<script>
var spreadsheet = ej.base.getComponent(document.getElementById('spreadsheet'), 'spreadsheet');
var saveInitiated;
function beforeSave(eventArgs) {
if (!saveInitiated) {
eventArgs.cancel = true; // Preventing default save action.
saveInitiated = true; // The "beforeSave" event will trigger for "saveAsJson" action also, so we are preventing for the "saveAsJson".
saveAsExcel(eventArgs);
}
};
function saveAsExcel(eventArgs) {
// Convert the spreadsheet workbook to JSON data.
spreadsheet.saveAsJson().then(Json => {
saveInitiated = false;
const formData = new FormData();
// Passing the JSON data to server to perform save operation.
formData.append('JSONData', JSON.stringify(Json.jsonObject.Workbook));
formData.append('saveType', 'Xlsx');
formData.append('fileName', 'Worksheet');
formData.append('pdfLayoutSettings', '{"fitSheetOnOnePage":false,"orientation":"Portrait"}');
// Using fetch API to invoke the server for save processing.
fetch('https://xxxxxxxxxxxxxxxxxxxxxxxxx.amazonaws.com/Prod/api/spreadsheet/save', {
method: 'POST', body: formData
}).then(response => {
if (response.ok) {
return response.blob();
}
}).then(data => {
const reader = new FileReader();
reader.onload = function () {
//Converts the result of the file reading operation into a base64 string.
const textBase64Str = reader.result.toString();
//Converts the base64 string into a Excel base64 string.
const excelBase64Str = atob(textBase64Str.replace('data:text/plain;base64,', ''));
//Converts the Excel base64 string into byte characters.
const byteCharacters = atob(excelBase64Str.replace('data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,', ''));
const byteArrays = [];
for (let i = 0; i < byteCharacters.length; i++) {
byteArrays.push(byteCharacters.charCodeAt(i));
}
const byteArray = new Uint8Array(byteArrays);
//creates a blob data from the byte array with xlsx content type.
const blobData = new Blob([byteArray], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' });
const blobUrl = URL.createObjectURL(blobData);
const anchor = document.createElement('a');
anchor.download = 'Sample.xlsx';
anchor.href = blobUrl;
document.body.appendChild(anchor);
anchor.click();
URL.revokeObjectURL(blobUrl);
document.body.removeChild(anchor);
}
reader.readAsDataURL(data);
});
});
};
</script>Save data as a Base64 string
In the Spreadsheet control, there is currently no direct option to save data as a Base64 string. You can achieve this by saving the Spreadsheet data as blob data and then converting that saved blob data to a Base64 string using FileReader.
You can get the Spreadsheet data as blob in the saveComplete event when you set the
needBlobDataas true andisFullPostas false in the beforeSave event.

}Configure JSON serialization options
Previously, when saving the Spreadsheet as a workbook JSON object using the saveAsJson method, the entire workbook with all loaded features were processed and saved as a JSON object.
Now, you have the option to selectively ignore some features while saving the Spreadsheet as a JSON object by configuring serialization options and passing them as arguments to the saveAsJson method. This argument is optional, and if not configured, the entire workbook JSON object will be saved without ignoring any features.
spreadsheet.saveAsJson({ onlyValues: true });| Options | Description |
|---|---|
| onlyValues | If true, includes only the cell values in the JSON output. |
| ignoreStyle | If true, excludes styles from the JSON output. |
| ignoreFormula | If true, excludes formulas from the JSON output. |
| ignoreFormat | If true, excludes number formats from the JSON output. |
| ignoreConditionalFormat | If true, excludes conditional formatting from the JSON output. |
| ignoreValidation | If true, excludes data validation rules from the JSON output. |
| ignoreFreezePane | If true, excludes freeze panes from the JSON output. |
| ignoreWrap | If true, excludes text wrapping settings from the JSON output. |
| ignoreChart | If true, excludes charts from the JSON output. |
| ignoreImage | If true, excludes images from the JSON output. |
| ignoreNote | If true, excludes notes from the JSON output. |
The following code snippet demonstrates how to configure the serialization options and pass them as arguments to the saveAsJson method:
<div id="Saveasjson">
<label id="Heading">Save As Json Options:</label> <br>
<input type="checkbox" id="valueOnly" onchange="toggleCheckboxes()"><label for="valueOnly">Only Values</label>
