Limits and behavior
Exports displayed cached values, not formulas or styles; formulas are not recalculated. 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.
Save an Excel worksheet as a CSV file
Extract worksheet values from an Excel-compatible XLSX file and export them into CSV text for data exchange.
Does CSV preserve Excel styling, multiple sheets and all formulas?
No. CSV contains tabular cell values, not a multi-sheet workbook with rich formatting.
