About this Tool
Use this Excel to CSV Converter to export worksheet data into plain CSV. The tool lets users choose a sheet, read cell values, preserve empty cells in the used range, and choose delimiter and quote options for the CSV output. It focuses on table values, with clear limits around formulas, macros, charts, styling, and very large workbooks.
Examples
- Worksheet: Orders Order ID Customer Total A-1001 Ada 39.90 A-1002 Ben 24.50
Frequently Asked Questions
Are my spreadsheet files uploaded to a server?
No. The tool parses, transforms, previews, and exports data locally in your browser without uploading your input.
Are Excel macros or formulas executed?
No. Spreadsheet tools read and write cell values only. Macros are not run, and a complete formula calculation engine is not promised.
Will formatting, charts, or workbook features be preserved?
Not reliably. These tools focus on table data. Charts, formulas, comments, complex formatting, and advanced workbook features may be ignored or simplified.
Can multiple worksheets be processed?
The interface lets the user select one worksheet at a time. Batch export can be considered later if it stays clear and browser-friendly.
What file sizes are practical in the browser?
Small and medium tables are the best fit. Very large files can use a lot of memory because parsing, previews, and exported results all live inside the browser tab.
