Support for large excel file >5GB using javascript

[nishantkainth]

Hi,
I am generating excel file in memory using writeBuffer() and then downloading the file. It works fine for small file but fails for larger files and it takes almost 8+ gb of memory while processing the information. I also tried using workbookwriter as below but getting error as "stream" is undefined. Please help me with some example.
I used it like mentioned in the document.

var options = {
  filename: fName + '.xlsx',
  useStyles: true,
  useSharedStrings: true
};
workbookObj.workbook = new ExcelJS.stream.xlsx.WorkbookWriter(options);

Best Regards
