XLSX.utils.sheet_to_json returning empty array

Hey,

I am trying to give our users the possibility to upload an XLSX file (through ng-file-uploader), and to convert this XLSX file to JSON data afterwards. The uploading of the file works fine, this is the result when I print $scope.file in the console:

When I try to use the sheet to json function, I get an empty array back, while there is a lot of data in the uploaded XLSX file.

In my code I use the following: XLSX.utils.sheet_to_json($scope.file);

This returns an empty array as said before. Is there something I’m forgetting or should execute differently?

Kind regards,

Thomas

@Xsmael I solved this setting a the name of the sheet you want to use and also the header, which might help you to identify each column.

var workbook = XLSX.read(bstr, {type:'binary'});
var form = XLSX.utils.sheet_to_json(workbook.Sheets[workbook.SheetNames[3]], {header:["headerName1","headerName2","headerName3"]});

Where workbook.SheetNames[3] is the name of my third sheet, which is the one I’m using in this example. I hope this helps you

@jvicensfarrus proving headers just outputs an array with provided headers, no other sheet data is prasent ? anything else we need to do ?

const wb = XLSX.read( bufferArray, { type: 'buffer' } );
      const wsname = wb.SheetNames[7];
      const ws = wb.Sheets[wsname];
      const data = XLSX.utils.sheet_to_json(ws, {
        raw : true,
        header : ['Date','Currency','Income','Expense','Fee','Balance','Reason','Remarks']
      });

@shamseerahammedm you could try to not use constants and creating the ‘ws’ directly within the wb.SheetName[7]

var wb = XLSX.read( bufferArray, { type: 'buffer' } );
var ws = wb.SheetNames[7];
var data = XLSX.utils.sheet_to_json(ws, {
        raw : true,
        header : ['Date','Currency','Income','Expense','Fee','Balance','Reason','Remarks']
 });
