How to concat blob variables in google appscript?

I am trying to concat contents of multiple spreadsheet's data and write that into a new MICROSOFT_EXCEL file.

My sample code is

var ss = SpreadsheetApp.getActive();



var url = "https://docs.google.com/feeds/download/spreadsheets/Export?key=" + "FILE_ID" + "&exportFormat=xlsx";

var url1 = "https://docs.google.com/feeds/download/spreadsheets/Export?key=" + "SECOND_FILE_ID" + "&exportFormat=xlsx";



var params = {

      method      : "get",

      headers     : {"Authorization": "Bearer " + ScriptApp.getOAuthToken()},

      muteHttpExceptions: true

    };



var blob = UrlFetchApp.fetch(url, params).getBlob();



var blob1 = UrlFetchApp.fetch(url1, params).getBlob();



var barr = blob.getBytes();

var barr1 = blob1.getBytes();



var combine = barr.concat(barr1);



var blbfnl = Utilities.newBlob(combine);



blbfnl.setName("my_new" + ".xlsx");

DriveApp.createFile(blob1);

This code is creating a file in '.xlsx' format but neither google sheet nor Microsoft Excel is able to read this file.

I can't use spreadsheet for final result as has cell limitation of 10 millions.

Could you please provide a light on where am I doing wrong?

What you're attempting will not work. Concatenating two arbitrary blobs will just result in an error. Your real issue is storing large data sets, and Google Sheets are ill-suited for that purpose. You may have to migrate to a more scalable database solution - but they are not likely to be free.

Yes, rather then concatenating blobs you may want to get the data in each sheet, merge that together using JS, then export the result.
