Sobre esta herramienta
Turn a plain CSV file into a proper Excel workbook, or export an .xlsx spreadsheet back to CSV for import into another system. The tool detects which direction to convert based on the file you choose, and everything runs locally so your data never leaves your device.
Does it work both ways?
Yes, choose a .csv file to get an .xlsx, or an .xlsx file to get a .csv — the tool detects the format automatically.
Are formulas or formatting preserved?
CSV has no concept of formulas or styling, so converting to CSV keeps values only; converting to Excel creates a plain single-sheet workbook.
Is my spreadsheet uploaded anywhere?
No, conversion happens entirely in your browser.
