The following example shows how to export the document as Word document (.docx).

Note: The Syncfusion Document Editor component’s document pagination (page-by-page display) can’t be guaranteed for all the Word documents to match the pagination of Microsoft Word application. For more information about why the document pagination (page-by-page display) differs from Microsoft Word

Export as blob

Document Editor also supports API to store the document into a blob. Refer to the following sample to export document into blob in client-side.

Copied to clipboard
import { DocumentEditor, FormatType, WordExport, SfdtExport } from '@syncfusion/ej2-documenteditor';

//Inject require modules for Export.
DocumentEditor.Inject(WordExport, SfdtExport);

let documenteditor: DocumentEditor = new DocumentEditor({ enableSfdtExport: true, enableWordExport: true, enableTextExport: true });

documenteditor.appendTo('#DocumentEditor');

documenteditor.open(sfdt);

document.getElementById('export').addEventListener('click', () => {
    //Export the current document as `Blob` object.
    documenteditor.saveAsBlob('Docx').then((exportedDocument: Blob) => {
      // The blob can be processed further
    });
});

For instance, to export the document as Rich Text Format file, implement an ASP.NET MVC web API controller using DocIO library by passing the DOCX blob. Refer to the following code example.

Copied to clipboard
    //API controller for the conversion.
    [HttpPost]
    public HttpResponseMessage ExportAsRtf()
    {
        System.Web.HttpPostedFile data = HttpContext.Current.Request.Files[0];
        //Opens document stream
        WordDocument wordDocument = new WordDocument(data.InputStream);
        MemoryStream stream = new MemoryStream();
        //Converts document stream as RTF
        wordDocument.Save(stream, FormatType.Rtf);
        wordDocument.Close();
        stream.Position = 0;
        return new HttpResponseMessage() { Content = new StreamContent(stream) };
    }

In client-side, you can consume this web service and save the document as Rich Text Format (.rtf) file. Refer to the following example.

Copied to clipboard
document.getElementById('export').addEventListener('click', () => {
    //Expor the document as `Blob` object.
    documenteditor.saveAsBlob('Docx').then((exportedDocument: Blob) => {
          // The blob can be processed further
          let formData: FormData = new FormData();
          formData.append('fileName', 'sample.docx');
          formData.append('data', exportedDocument);
          saveAsRtf(formData);
    });
});

function saveAsRtf(formData: FormData): void {
    //Send the blob object to server to process further.
    let httpRequest: XMLHttpRequest = new XMLHttpRequest();
    httpRequest.open('POST', '/api/DocumentEditor/ExportAsRtf', true);
    httpRequest.onreadystatechange = () => {
        if (httpRequest.readyState === 4) {
            if (httpRequest.status === 200 || httpRequest.status === 304) {
                if (!(!navigator.msSaveBlob)) {
                    navigator.msSaveBlob(httpRequest.response, 'sample.rtf');
                } else {
                    let downloadLink: HTMLAnchorElement = document.createElementNS('http://www.w3.org/1999/xhtml', 'a') as HTMLAnchorElement;
                    download('sample.rtf', 'rtf', httpRequest.response, downloadLink, 'download' in downloadLink);
                }
            } else {
                console.error(httpRequest.response);
            }
        }
    }
    httpRequest.responseType = 'blob';
    httpRequest.send(formData);
}

//Download the document in client side.
function download(fileName: string, extension: string, buffer: Blob, downloadLink: HTMLAnchorElement, hasDownloadAttribute: Boolean): void {
    if (hasDownloadAttribute) {
        downloadLink.download = fileName;
        let dataUrl: string = window.URL.createObjectURL(buffer);
        downloadLink.href = dataUrl;
        let event: MouseEvent = document.createEvent('MouseEvent');
        event.initEvent('click', true, true);
        downloadLink.dispatchEvent(event);
        setTimeout((): void => {
            window.URL.revokeObjectURL(dataUrl);
            dataUrl = undefined;
        });
    } else {
        if (extension !== 'docx' && extension !== 'xlsx') {
            let url: string = window.URL.createObjectURL(buffer);
            let isPopupBlocked: Window = window.open(url, '_blank');
            if (!isPopupBlocked) {
                window.location.href = url;
            }
        }
    }
}
