Convert Excel (XLSX) to CSV
Convert Excel XLSX/XLS files to CSV online — pick the sheet, get clean comma-separated output.
How to use Excel to CSV
Drop a workbook, pick which sheet to export if there's more than one, and download standards-clean CSV: values as displayed, commas and quotes escaped correctly, UTF-8 throughout. It's the file every import screen, database loader and script actually wants.
- Drop your file into the box above, or click it to browse. You can also paste from the clipboard.
- Adjust the options to taste — the defaults are sensible for most cases.
- Press Process and watch the progress bar; everything runs on your device.
- Download your result — individually, or as a ZIP when there are several files.
Like every tool on ImageCompressorKits, this runs 100% in your browser: your file is never uploaded to any server, which makes it safe to use even with private documents — and it keeps working if you go offline after the page loads.
Frequently asked questions
Do my formulas get exported?
CSV stores values, not formulas — you get each cell's calculated result, which is what importing systems expect.
My data contains commas — will that break the CSV?
No. Fields containing commas, quotes or line breaks are quoted and escaped per the CSV standard, and any compliant parser reads them back perfectly.
Is this tool really free?
Yes — completely free, with no signup, no watermark, and no file limits beyond what your device's memory can handle.
Are my files private?
Yes. Processing happens locally in your browser via JavaScript; nothing is transmitted or stored. See our privacy policy for the full picture.
