FAQs
The columns look wrong after converting.
That usually means the wrong delimiter was picked. If your spreadsheet program also splits everything into one column, try semicolon or tab instead.
Are numbers and dates preserved?
Yes — numeric-looking cells are stored as real numbers in the workbook, and dates stay as date text, so Excel can work with them.
Is my file uploaded anywhere?
No. This tool runs entirely in your browser — your file is never sent to any server.
