Is my data safe when converting Excel to CSV?

Yes, your data is completely safe. All processing happens locally on your device using browser-based technology. We never upload your files to any server, so your sensitive data never leaves your computer. Once you close the tab, no trace of your file remains.

What Excel file formats are supported?

Our converter supports both modern Excel formats (.xlsx) and legacy Excel formats (.xls). It also handles Excel files with multiple sheets, allowing you to select and convert specific sheets individually.

Can I convert large Excel files?

Yes, you can convert large Excel files depending on your device's available memory. Since processing happens locally, larger files may take a few seconds longer. For extremely large files (over 100MB), we recommend splitting them into smaller portions for optimal performance.

What delimiter options are available for CSV output?

You can choose from multiple delimiter options including comma (,), semicolon (;), tab, and pipe (|). Comma is the standard delimiter, but semicolon is commonly used in European regions. Select the delimiter that matches your target application's requirements.

Will special characters and formulas be preserved in the CSV?

Special characters and text are fully preserved in UTF-8 encoding. However, Excel formulas will be converted to their calculated values in the CSV file, as CSV format doesn't support formulas. This is the standard behavior for CSV conversion across all tools.
