XLS to Markdown Table Converter
Convert legacy Excel 97–2003 (.xls) files to GitHub-Flavored Markdown tables. Works in your browser with no upload or software install.
Legacy .xls files (the Excel Binary Workbook format used before Excel 2007) are
still common in enterprise environments. This tool uses SheetJS to parse both .xls
and .xlsx files entirely in your browser, converting them to GitHub-Flavored
Markdown tables without any server-side processing.
The output is valid GFM table syntax that renders correctly in GitHub READMEs, Notion pages, Obsidian notes, GitLab wikis, and any other Markdown-aware renderer. Numeric columns are right-aligned automatically.
XLS vs XLSX: which format to use?
.xls is the legacy binary format (Excel 97–2003). .xlsx is the modern
XML-based format (Excel 2007+). Both are supported by this tool via SheetJS. If you have a
choice, .xlsx is preferred — it is smaller, more portable, and better supported by
open-source libraries. But if your files are old .xls exports, this converter
handles them just as well.
