Frequently Asked Questions
Frequently asked questions about merging and matching Excel files.
How does matching by column work in SheetClean AI?
The Agent identifies the shared key column (such as User ID, Product SKU, or Customer Email). It sanitizes both sides to remove ghost whitespace, unifies data types, and matches records reliably.
What happens if a key exists in one sheet but not the other?
The Agent highlights unmatched candidate rows so you can review orphan records before exporting the unified dataset.
Can I merge CSV files with Excel (.xlsx) files?
Yes. The matching engine seamlessly supports mixing XLSX, XLS, and CSV files.
Do I need to write VLOOKUP, INDEX/MATCH, or XLOOKUP formulas?
No. The Agent performs an automated deterministic join on the underlying data and provides a ready-to-use unified spreadsheet.
How large can the merged files be?
You can match datasets up to 100,000 rows. Processing is optimized for rapid in-memory operations.
Is it safe for proprietary inventory and revenue data?
Yes. Files are processed in memory and wiped immediately. We enforce strict end-to-end data privacy.
Can I preview the merged columns before paying?
Yes. The diagnostic profile and match verification diff table are 100% free to inspect.
