Excel to CSV
Open an XLSX workbook locally, choose a worksheet, and export its cell values as CSV.
What this tool does
The XLSX reader resolves workbook sheets, shared strings, inline strings, booleans, formulas with cached values, and ordinary numeric cells directly from the OOXML package.
What to expect
CSV stores values only. Formatting, formulas themselves, charts, images, macros, comments, merged-cell presentation, and workbook features are not preserved. Excel date serials may remain numeric when style metadata is ambiguous.
