Frequently Asked Questions
What is the difference between Excel and CSV files?
Excel files (.xlsx, .xls) can contain multiple worksheets, formatting, formulas, and charts. CSV (Comma-Separated Values) files are plain text files that contain only data separated by commas, making them universally compatible but without formatting.
Is it safe to upload my Excel files?
Yes, absolutely! Our converter processes files entirely in your browser using JavaScript. Your files never get uploaded to our servers, ensuring complete privacy and security of your data.
What Excel file formats are supported?
Our tool supports both modern Excel formats (.xlsx) and legacy Excel formats (.xls). You can convert files created in any version of Microsoft Excel.
Can I convert multiple Excel files at once?
Yes! Our batch conversion feature allows you to select and convert multiple Excel files simultaneously, saving you time and effort.
What happens to formulas and formatting?
CSV files only contain raw data values. Formulas are converted to their calculated values, and formatting (colors, fonts, etc.) is removed as CSV is a plain text format.
Is there a file size limit?
The only limit is your browser’s memory capacity. Our tool can handle large Excel files, but very large files (100MB+) may take longer to process depending on your device’s performance.
How are multiple worksheets handled?
If your Excel file contains multiple worksheets, each worksheet will be converted into a separate CSV file. You’ll receive individual downloads for each worksheet.
Do I need to install any software?
No installation required! Our Excel to CSV converter runs entirely in your web browser. Just visit this page and start converting immediately.
