Excel to CSV Converter

Frequently asked questions

Can I choose which worksheet to export?

Yes. After you upload a workbook, the tool lists every sheet it contains. Pick one and the CSV is generated from that sheet. The whole conversion runs in your browser, so your spreadsheet is never uploaded.

Will special characters and accented letters survive the conversion?

Yes. The downloaded CSV file is written with a UTF-8 byte-order mark so Excel re-opens it with the correct encoding. Characters such as accented letters, currency symbols, and CJK text are preserved. If you open the file in a plain-text editor you may see a BOM at the start, but most tools handle it automatically.

What happens to Excel formulas when converting to CSV?

CSV is a plain-text format and cannot store formulas. The converter exports the calculated value that Excel has already computed, not the formula itself. If a cell shows 42, the CSV contains 42, regardless of the formula that produced it.

Is there a file size limit?

There is no hard limit set by this tool. The practical ceiling is your browser memory, which is typically several hundred megabytes. Very large workbooks (tens of thousands of rows) convert quickly because the parsing library streams data rather than loading it all at once. If the page becomes unresponsive, try exporting one sheet at a time.
