  2. Convert and download the XLSX workbook.
  3. Open it in Excel or another compatible spreadsheet app.

Frequently asked questions

Are leading zeros preserved?

Yes. CSV cells are written as text, so values such as 00123 stay intact.

Are formulas calculated?

No. Input is written as text rather than executable formulas. CSV files with other delimiters must be converted first.
