Convert Excel to CSV
Export any sheet from an .xlsx or .xls file as a clean, UTF-8 .csv file.
Privacy & processing: Runs entirely in your browser — your file is never uploaded to a server.
How to use this tool
- Upload your Excel file
- Choose which sheet to export
- Preview the CSV output
- Download the .csv file
Common use cases
- Preparing data for import into another system
- Sharing a lightweight, plain-text version of a sheet
- Feeding data into scripts or pipelines
Limitations
Only one sheet can be exported per CSV, since CSV itself has no concept of multiple sheets — export each sheet you need separately.
FAQ
What happens to multiple sheets in my workbook?
You choose which single sheet to export — CSV format can't represent more than one sheet, so multi-sheet workbooks need one export per sheet.
Does this preserve cell formulas?
No — CSV stores only calculated values, not formulas, since the format has no way to represent them.
Is this processed on a server?
No — conversion happens entirely in your browser.
