Limits and behavior
Copies cell values, formulas and common styles into uniquely named worksheets. Charts, pivots, external links and embedded drawings are not merged; formulas referencing renamed worksheets are rejected. 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.
Join worksheets from multiple Excel files
Collect compatible worksheets into a single XLSX workbook for easier file organization.
Does merging sheets automatically reconcile formulas and references?
No. Cross-workbook formulas and references can require manual adjustment; review the merged workbook.
