(Large files) 73500+ rows: RangeError: Maximum call stack size exceeded

Hello,

I’m using the node version with below code:

const readXlsxFile = require('read-excel-file/node');

(async () => {
  const rows = await readXlsxFile('2019_07_24.xlsx');

  console.log(rows);
})();

Parsing a ~73500 rowed file, attaching. But XPATH module throws the exception: Maximum call stack size exceeded. File uploaded below.

2019_07_24.xlsx

This post is for anyone trying to read a larger excel sheet. I finally got a solution that was able to read my 122k rows excel sheet using https://github.com/SheetJS/js-xlsx :

const workbook = XLSX.read(microstrategyFile. tempFilePath, { type: 'file' });
const [firstSheetName] = workbook.SheetNames;
const worksheet = workbook.Sheets[firstSheetName];

const rows = XLSX.utils.sheet_to_json(worksheet, {
    raw: true, // Use raw values (true) or formatted strings (false)
    header: 1, // Generate an array of arrays ("2D Array")
});

I must say that the above solution is pretty memory intensive. It drove a hobby dyno on Heroku well beyond the 512mb memory limit just by running the above lines.

Latest changes: I’ve removed xpath in read-excel-file@5.2.0, so the error shouldn’t reappear.
