In Document Editor, the documents are stored in its own format called Syncfusion Document Text (SFDT).
The following example shows how to open SFDT data in Document Editor.
var documenteditor = new ej.documenteditor.DocumentEditor({ });
documenteditor.appendTo('#DocumentEditor');
var sfdt ={
"sections": [
{
"blocks": [
{
"inlines": [
{
"characterFormat": {
"bold": true,
"italic": true
},
"text": "Hello World"
}
]
}
],
"headersFooters": {
}
}
]
};
documenteditor.open(JSON.stringify(sfdt));<!DOCTYPE html><html lang="en"><head>

This library helps you to convert word documents (.dotx,.docx,.docm,.dot,.doc), rich text format documents (.rtf), and text documents (.txt) into SFDT format. Refer to the following example.
import { DocumentEditor } from '@syncfusion/ej2-documenteditor';
let documenteditor: DocumentEditor = new DocumentEditor();
documenteditor.appendTo('#DocumentEditor');
document.getElementById('file_upload').setAttribute('accept', '.dotx,.docx,.docm,.dot,.doc,.rtf,.txt,.xml,.sfdt');
document.getElementById("import").addEventListener("click", (): void => {
document.getElementById('file_upload').click();
});
document.getElementById('file_upload').addEventListener("change", (e: any): void => {
if (e.target.files[0]) {
let file = e.target.files[0];
if (file.name.substr(file.name.lastIndexOf('.')) !== '.sfdt') {
loadFile(file);
}
}
});
function loadFile(file: File): void {
let ajax: XMLHttpRequest = new XMLHttpRequest();
ajax.open('POST', 'https://localhost:4000/api/documenteditor/Import', true);
ajax.onreadystatechange = () => {
if (ajax.readyState === 4) {
if (ajax.status === 200 || ajax.status === 304) {
// open SFDT text in document editor
documenteditor.open(ajax.responseText);
}
}
}
let formData: FormData = new FormData();
formData.append('files', file);
ajax.send(formData);
}Here’s how to handle the server-side action for converting word document in to SFDT.
[AcceptVerbs("Post")]
public string Import(IFormCollection data)
{
if (data.Files.Count == 0)
return null;
Stream stream = new MemoryStream();
IFormFile file = data.Files[0];
int index = file.FileName.LastIndexOf('.');
string type = index > -1 && index < file.FileName.Length - 1 ?
file.FileName.Substring(index) : ".docx";
file.CopyTo(stream);
stream.Position = 0;
WordDocument document = WordDocument.Load(stream, GetFormatType(type.ToLower()));
string sfdt = Newtonsoft.Json.JsonConvert.SerializeObject(document);
document.Dispose();
return sdft;
}
internal static FormatType GetFormatType(string format)
{
if (string.IsNullOrEmpty(format))
throw new NotSupportedException("EJ2 DocumentEditor does not support this file format.");
switch (format.ToLower()) {
case ".dotx":
case ".docx":
case ".docm":
case ".dotm":
return FormatType.Docx;
