Excel to CSV Converter

Frequently Asked Questions

What Excel formats are supported?

Our Excel to CSV converter supports both modern (.xlsx) and legacy (.xls) Excel file formats. Simply upload your file and the tool will automatically detect the format and parse it correctly. All versions of Microsoft Excel files are supported.

Can I convert files with multiple sheets?

Yes! If your Excel file contains multiple sheets, you can select which sheet to convert from the dropdown menu. The tool displays all available sheets and shows row/column counts for each. Each sheet can be converted individually to CSV format.

What delimiters can I use?

You can choose from comma (,) for standard CSV, semicolon (;) for European CSV, tab (\t) for tab-separated values, or pipe (|) for pipe-separated values. The delimiter you choose depends on your target application or region.

Should I include headers?

Select "Yes" for "Include Headers" to keep the first row as column headers - this is recommended for most use cases. Select "No" if you only want data rows without headers, useful when headers are predefined or when appending to existing CSV files.

Is my data secure when using this tool?

Absolutely! All conversion happens entirely in your browser. Your Excel files are never uploaded to any server. This ensures complete privacy and security for sensitive business data, customer information, or confidential records. The tool works 100% client-side using JavaScript.

How are formulas and formatting handled?

The converter extracts the actual values from cells, not the formulas themselves. If a cell contains a formula, the converted CSV will contain the calculated result. Basic text formatting is preserved, but complex formatting (colors, fonts, borders) is removed in the CSV output.
