- Adjust the options shown.
- Select the action button and wait for it to finish.
- Review the result, then download it.
What to expect
A new file is created. Your original file is never modified.
- Only .xlsx workbooks are supported. Save .xls and .ods files as .xlsx first.
- Formatting, charts, images and formulas are not exported — only cell values.
Frequently asked questions
What happens to formulas?
The cached result saved in the file is exported. The tool never recalculates formulas.
Are cells protected against CSV formula injection?
Yes. Text cells starting with = + - or @ get a leading apostrophe so spreadsheets don't treat them as formulas (you can switch this off).
Do I need to create an account?
No. Every tool works without sign-up or login.
Is it safe for confidential documents?
Files are processed locally in your browser and never uploaded. Close the tab or select Clear to release them from memory.
