Yes, absolutely. All file processing and data comparison happens locally in your web browser. Your data is never uploaded to our servers, ensuring 100% privacy and security.

The comparison table uses colors to highlight differences: Green indicates a perfect match between both files, Red highlights rows with different values or modifications, and Yellow/Orange marks rows that exist in one file but are missing from the other.
Yes, once you upload a file with multiple sheets, a dropdown menu will appear allowing you to select exactly which sheet you want to use for the comparison.
