Yes, your data is completely secure. All file processing happens locally in your browser using JavaScript. Your Excel files are not uploaded to any server, ensuring complete privacy and data security.

What happens with very large Excel files? +

Large files (over 10MB) cannot be uploaded due to browser limitations. For files with many rows, use the row limiting options to display only the first 50, 100, or 500 rows for better performance. You can always select "All rows" for smaller datasets.
