Limits and behavior
First row is treated as a header and retained. Formulas are rejected to prevent stale references after row changes. Local processing. Maximum 10 MB per file, 25 MB total; expanded ZIP contents at most 50 MB and 2,000 entries. Spreadsheet limit: 10,000 cells and 2,000 rows per sheet. Macros are never executed. Originals are unchanged. Cancellation stops active PDF renders and discards stale results; a synchronous library step finishes before the browser can handle cancellation.
Deduplicate spreadsheet rows using cell values
Choose a relevant column or cell selection to remove duplicate rows from an XLSX table.
Can this detect duplicates with different spelling or spacing?
The matching rules use selected cell values rather than fuzzy record matching; check values before and after processing.
