Frequently asked questions

Which separator should I choose?

Comma is the standard. In countries where a comma is the decimal mark, such as much of Europe, Excel expects semicolons, so choose semicolon if the CSV will be opened in Excel there. Tab-separated works well for pasting into other programs.

What happens to formulas and formatting?

CSV stores only values, so each cell is saved as the value Excel shows, such as 1,250.00 or 15/03/2026. Formulas, colors, fonts and merged cells are not kept.

Why do Sinhala, Tamil or accented letters look wrong in Excel?

Excel sometimes guesses the wrong text encoding for CSV files. Keep “Add UTF-8 marker for Excel” ticked, and Excel will read every language correctly.

Can I convert every sheet at once?

Yes. Choose “All sheets” and you'll get a ZIP with one CSV file per sheet.
