XLS to Markdown Converter
Open old .xls workbooks and convert any sheet to a Markdown table — no Excel
required, no upload, no signup.
The legacy .xls format (Excel 97-2003) is still widely used in enterprise
environments, accounting software, and older data pipelines. While modern Excel defaults to
.xlsx, many systems export .xls exclusively and converting these
files typically requires a full Excel installation.
This converter uses SheetJS, which supports the legacy BIFF8 binary format used by
.xls files. Sheets, cell values, formulas (evaluated results), merged cells,
and number formatting are all read correctly. The output is a standard GFM Markdown table
that you can paste directly into any Markdown-aware editor.
