Why it matters

Financial files deserve better than an upload site

Account numbers, balances and client figures shouldn't be sent to a free converter's server. This one runs entirely in your browser and never receives your file.

FAQ

Questions

Will negative numbers in brackets be kept?

Yes. With Numbers set to As shown, (1,250.50) stays (1,250.50). With Raw values it becomes -1250.5, which is what most software imports expect.

Can I convert a workbook with many sheets?

Yes. Download all sheets as a zip with one CSV per sheet, named after each sheet.

Are formulas kept?

A CSV holds values only, so each formula becomes the result Excel last saved, as with Excel's own Save As CSV.

Is my financial data uploaded?

No. It is converted in your browser and never sent anywhere.
