Frequently Asked Questions

Is my CSV file uploaded to a server?
No. All conversion happens entirely in your browser. Your files never leave your device, ensuring complete privacy.
What delimiter should I select?
Select the delimiter used in your CSV file. Comma is most common, but European files often use semicolon. If you see data in wrong columns, try a different delimiter.
Will formulas be preserved?
CSV files don't contain formulas - they only store raw data. The Excel file will contain your data as values, and you can add formulas after opening it in Excel.
What's the maximum file size?
Since processing happens in your browser, the limit depends on your device's memory. Most devices can handle files up to several hundred megabytes.
Can I open the file in Google Sheets?
Yes! The generated .xlsx file is compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications.
