Questions & answers
01Why does Excel open my CSV in one column?
Excel guesses the delimiter based on regional settings and often gets it wrong. Converting to XLSX first produces a spreadsheet with proper columns everywhere.
02Is my data uploaded anywhere?
No. The XLSX file is built locally in your browser, so exports containing customers, prices or credentials never leave your device.
03Is CSV to Excel free to use?
Yes, CSV to Excel is completely free, with no sign-up and no usage limits. It runs entirely in your browser, so your data never leaves your device.
