  I am trying this export to .xlsx example for my application. http://help.grapecity.com/spread/SpreadSheets10/JavascriptLibrary~GC.Spread.Excel.IO~save.html

  Here the code that i am trying.

  
          vm.spread = vm.spread = new GC.Spread.Sheets.Workbook($document[0].getElementById('test_element'), { sheetCount: 1 });
  
  
  	var fileName = 'test.xlsx';
          var json = JSON.stringify(vm.spread.toJSON());
          var excelIO = new GC.Spread.Excel.IO();
          excelIO.save(json, function (blob) {
                  console.log(blob)  // returning : Blob(6280) {size: 6280, type: "application/zip"}
                  saveAs(blob, fileName);
          }, function (e) {
                  console.log(e);  // Returning error : {errorCode: 1, errorMessage: "Incorrect file format."}
          });

  Hello,

  Could you please clarify which version of SpreadJs library are you using?

  As here is the documentation link for the latest version:-
  
  http://help.grapecity.com/spread/SpreadSheets11/webframe.html#excelclient.html

  Request you to please share a small working sample replicating the issue so that we can investigate this issue further.

  Thanks,
