About Excel to CSV Converter

Convert the first worksheet, or name a sheet, to UTF-8 CSV on your device. CSV contains displayed cell values, not styles, formulas, multiple sheets or Excel features. Spreadsheet formula protection is enabled by default and can change values.

How to use it

  1. Choose an XLSX file and optionally name a worksheet.
  2. Choose whether to protect formula-like values.
  3. Convert, download and verify the UTF-8 CSV.

Frequently asked questions

Does it export every sheet?

No. It exports the first worksheet unless you name a different one.

Why are some values prefixed with an apostrophe?

The default safety option protects against formula injection in spreadsheet apps. Disable it only for trusted data if exact values matter.
