    Excel to CSV converter

    Export workbook data for databases, accounting imports or spreadsheet review. Each selected worksheet becomes its own CSV. Formatted mode uses stored number formats; raw mode keeps numeric values and Excel date serials. Regional date displays can differ from Excel. Merged ranges keep only stored cells; styling-only trailing rows are omitted. Exported data is limited to 1,000,000 cell positions and 20 MB.

    How to use this tool

    1. Upload an XLSX workbook or import its direct public URL. Try the example with dates, negative amounts and a formula without a saved result.
    2. Choose formatted or raw values, visible or all worksheets, and a CSV separator. Create the exports and review the table previews.
    3. Download individual CSV files or the ZIP. Check workbook-review.csv before importing. Import identifier columns as text in Excel to preserve leading zeroes.

    Output and limitations

    Convert an XLSX workbook to separate CSV files for each worksheet. Choose formatted or raw saved values, include hidden sheets, and download a ZIP, JSON and review report.

    One XLSX up to 5 MB and 20 sheets; 10,000 rows and 256 columns per worksheet. XLS, XLSB, XLSM and encrypted files are unsupported. Formulas use saved results only. Hidden rows and columns are included; hidden sheets are optional. Formatting, charts and macros are not exported.

    Will CSV keep dates, hidden data and spreadsheet formatting?

    CSV contains cell values only. Hidden rows and columns are included. Hidden worksheets are excluded unless selected; chart sheets are skipped. Raw dates remain serial numbers using the workbook’s 1900 or 1904 date system. Formula-like text receives an apostrophe in CSV for safety; JSON keeps the selected values without that prefix.

    Are formulas calculated during conversion?

    No. Formulas are never evaluated. Existing saved results are exported; a formula with no saved result becomes blank and is counted in the report. Recalculate and save the workbook in Excel before exporting if results are missing.

    What if processing fails?

    Check the supported formats and file limits, then try a smaller file. Keep an original copy. A clear error message will explain an unsupported input or an unavailable processing service.
