Excel to CSV
Excel to CSV is a free online file converter that turns Excel (.xlsx/.xls) files into CSV format. You can pick which worksheet to convert, choose the delimiter (comma, semicolon, tab, or pipe), and decide whether to include the header row.
Files are parsed and converted locally in your browser — nothing is uploaded, so financial or customer spreadsheets stay private. Free with no registration, it's ideal when you need Excel data in CSV form for databases, scripts, or systems that only accept CSV.
How to Use
- Click to upload or drop an .xlsx/.xls file
- Select the worksheet to convert from the dropdown
- Choose a delimiter and toggle the header row option
- Click convert and download the resulting CSV file
FAQ
Is the Excel to CSV converter free?
Yes, it's completely free with no conversion limits and no account needed.
Is my Excel file uploaded to a server?
No. The file is parsed and converted entirely in your browser, so spreadsheets with sensitive data never leave your device.
How are workbooks with multiple sheets handled?
After upload, the tool lists every worksheet in the file. Pick the one you need from the dropdown; to export several sheets, convert and download them one at a time.
Can I change the CSV delimiter?
Yes. Besides the default comma, you can choose semicolon, tab, or pipe, so the output matches whatever format your target system expects.
