Is my Excel data secure when using this tool?

Yes, all processing happens in your browser - your files never leave your computer. We don't store or upload your data to any servers.

Can I perform VLOOKUP between multiple sheets in the same file?

Yes, you can use the same file for both main and lookup data by selecting different sheets within the same uploaded file.

The tool can handle files up to 10MB efficiently. For larger files, consider splitting them into smaller chunks for better performance.

Currently, the tool specializes in VLOOKUP operations. We plan to add INDEX-MATCH functionality in a future update.

Yes! Simply select multiple columns in the 'Select Value Column to Return' dropdown to retrieve multiple values at once.
