File content not appearing

[kalideir]

I am dynamically creating an Excel file using RNFS and XSLX modules. However, when I open the file with this module the content seems as if the file is totally empty. But when I share the same file through its path to google drive using react-native-share, I am able to see the content.

Any ideas?

Here is the code for creating the file

const exportNewSession = async (filename: string, data: Row[]) : Promise<void> => {
  const ws = await XLSX.utils.json_to_sheet(data);
  const wb = await XLSX.utils.book_new();
  await XLSX.utils.book_append_sheet(wb, ws, 'sheet1');
  const wbout = await XLSX.write(wb, { type: 'binary', bookType: 'xlsx' });
  const file = `${`${DocumentDirectoryPath}/history/${filename}`}`;
  console.log('file exported ^');
  return writeFile(file, wbout, 'ascii');
};

And here I try to open the same file:

const path = `${`file://${DocumentDirectoryPath}/history/${filename}`}`;
FileViewer.open(path)
      .then(() => {
        // success
      })
      .catch((error) => {
        // error
      });
