namespace syncfusion_test.Controllers{
public class ImportController : Controller{

Stream stream = new MemoryStream();
int index = file.FileName.LastIndexOf('.');
var type = index > -1 && index < file.FileName.Length - 1 ?
file.FileName.Substring(index) : ".docx";
stream.Position = 0;

WordDocument document = new WordDocument(stream,GetFormatType(type));
var sfdt = Newtonsoft.Json.JsonConvert.SerializeObject(document);
return Ok(sfdt);


static FormatType GetFormatType(string format){

Thank you for contacting the Syncfusion support. 

## Import word document 
To convert the word document to Json, you have to use the nuget Syncfusion.EJ2.WordEditor.AspNet.Core. 
In provided sample code, you have referred the word document from Syncfusion DocIO. 
Please refer the below sample which contains code for Document importing. 
Please let me know if you have any questions.
