FAQ

XLSX to CSV — common questions

How do I convert Excel to CSV for free?

Upload your .xlsx to FixTheFile and select Convert to CSV.

Which sheet gets converted?

The first (active) sheet in the workbook.

Are formulas included?

Calculated values are exported, not the formulas themselves.

Does formatting carry over?

No — CSV is plain text, so colors, fonts, and merged cells are not preserved.

Can I convert older .xls files?

Currently .xlsx only. Save .xls files as .xlsx in Excel first.
