Convert Excel to CSV
Turn an Excel workbook (.xlsx) into CSV files for importing into accounting software, databases, email tools or Google Sheets. Pick a sheet, check the preview and download, or get every visible sheet in one ZIP. The file is converted in your browser and never uploaded.
Everything runs on your device. Nothing you add or type is sent to any server.
How to use it
- 01
Drop your .xlsx file into the box above, or click to choose it.
- 02
Pick the sheet. The preview shows exactly what the CSV will contain.
- 03
Choose the separator and whether values should look as in Excel or be plain numbers.
- 04
Press Download CSV for this sheet, or the ZIP button for all visible sheets.
Values as shown, or plain values
As shown in Excel writes each cell the way you see it: 1,234.50, 12.5%, 01/04/2024. That is what most people expect when they open the CSV again. Plain values writes what is stored underneath: 1234.5, 0.125 and 2024-04-01, with no rounding from number formats. Choose plain values when the file goes into software or a database that has to calculate with it.
Formulas are written as their saved result, not as the formula. Merged cells keep their value in the first cell only.
Hindi that opens correctly
The CSV is always saved as UTF-8, which can hold every language. Excel, however, opens a UTF-8 CSV normally only when the file starts with a small marker (a BOM); without it, Hindi may show as strange symbols when you double-click the file. The marker is on by default. Turn it off only if the system you upload to rejects it, as some import tools do.
Which separator to choose
Comma is the standard choice. Semicolon suits software set up for countries that write decimals with a comma. Tab creates a .tsv file that pastes cleanly into spreadsheets, and pipe is used by some upload formats. Values that contain the separator, quotes or line breaks are quoted automatically, so columns never shift.
Frequently asked questions
Can I convert all sheets at once?
Yes. When the workbook has more than one visible sheet with data, the ZIP button saves one CSV per sheet, named after the sheet, in a single download. Hidden sheets are left out so they are not shared by accident; you can still pick one from the list and download it on its own.
Is my file uploaded?
No. Reading the workbook and writing the CSV both happen in your browser. Nothing is sent to a server.
Why can't it open my .xls file?
Excel 97–2003 .xls files use an old binary format this browser tool cannot read, and some bank downloads named .xls are really web pages. Open the file in Excel or Google Sheets, save it as .xlsx and convert that copy.
