Free online XLSM to CSV converter

A database import tool or reporting system may accept CSV files but reject macro-enabled Excel workbooks. Exporting an XLSM workbook provides tabular text data for import or exchange without including its VBA macros or workbook layout.

What the XLSM format is

XLSM is a macro-enabled Microsoft Excel workbook format based on Office Open XML. It can contain multiple worksheets, formulas, formatting, and VBA macros. Excel users commonly use it for spreadsheets that automate tasks; compatible programs such as LibreOffice Calc can open many XLSM files, though macro behavior may differ.

What the CSV format is

CSV (comma-separated values) is plain text arranged as rows and fields. Its simple structure is widely supported by databases, data-processing tools, and spreadsheet applications, making it useful for importing and exchanging tabular data. A CSV file represents one worksheet or table and does not retain formatting, formulas as formulas, macros, or other workbook features.

How to convert an XLSM file

Online on 101convert.com

1. Upload the XLSM file to the converter on this page.
2. Before converting, set the column separator, character encoding, and sheets as needed. You can convert several files in one batch; the page shows the per-file size limit.
3. Start the conversion and download the resulting CSV file or files.

The conversion runs on the server with LibreOffice.

Offline with desktop software

LibreOffice Calc is free and runs on Windows, macOS, and Linux. Open the workbook and choose File → Save As. Select Text CSV (.csv) as the file type, save, then confirm the CSV format if prompted. In the export dialog, choose the character set and field delimiter. Calc exports the current sheet only; export each required sheet separately.

Microsoft Excel for Windows or macOS can also save XLSM data as CSV. Open the workbook, choose File → Save As, and select a CSV option, such as CSV UTF-8 when available. Confirm the format warning if prompted. Excel exports the active worksheet only, so save each sheet you need separately.

Quality and compatibility

CSV exports cell data, not workbook features: macros and formatting are discarded, and formulas are normally represented by their calculated results. Check the exported sheet and delimiter; a delimiter mismatch can shift data into the wrong columns. Choose an encoding supported by the receiving program, or non-ASCII characters may display incorrectly. Verify important formula results and values after conversion, especially when the workbook depends on Excel-specific functions or macros.
