XLSX to Markdown
About XLSX to Markdown
Convert Excel (.xlsx) spreadsheets to GitHub-Flavored Markdown tables, entirely in your browser.
Pasting a spreadsheet into a README, wiki page, or GitHub issue usually means manually formatting a Markdown table by hand. This tool parses the XLSX workbook structure directly in your browser via a Rust-based WebAssembly parser and outputs GitHub-Flavored Markdown tables, no upload required.
