Convert word documents into SFDT

You can convert word documents into SFDT format using the .NET Standard library Syncfusion.EJ2.WordEditor.AspNet.Core by the web API service implementation. 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;
        case ".dot":
        case ".doc":
            return FormatType.Doc;
        case ".rtf":
            return FormatType.Rtf;
        case ".txt":
            return FormatType.Txt;
        case ".xml":
            return FormatType.WordML;
        default:
            throw new NotSupportedException("EJ2 DocumentEditor does not support this file format.");
    }
}
