XLSX to Markdown Converter

Convert XLSX Spreadsheets to Markdown Tables

Need to display spreadsheet data in your documentation, README file, or website? Our XLSX to Markdown converter transforms Excel spreadsheets into clean, readable Markdown tables that work anywhere.

Why Use Markdown Tables Instead of XLSX?

• Universal Compatibility: Markdown tables work on GitHub, GitLab, static sites, and documentation platforms
• Plain Text Format: Perfect for version control with Git - see exactly what changed
• No Software Needed: View and edit with any text editor, no Excel required
• Lightweight: Markdown files are 100x smaller than XLSX files
• SEO Friendly: Search engines can read and index Markdown tables easily
• Responsive: Markdown tables adapt to different screen sizes on web pages

How the XLSX to Markdown Conversion Works

Our converter uses the powerful SheetJS library to parse XLSX files entirely in your browser:

1. Your .xlsx file is read and parsed using JavaScript
2. Each worksheet is extracted and converted to structured data
3. The data is formatted using Markdown table syntax (pipes and hyphens)
4. Multiple sheets are separated with headings for clarity
5. The output is displayed instantly with copy and download options

Perfect For

• Developer Documentation: Convert API parameter tables, error codes, or configuration options
• GitHub Projects: Add feature comparison tables, roadmap tables, or compatibility matrices to README files
• Static Site Generators: Create data tables for Jekyll, Hugo, Gatsby, or Next.js documentation
• Technical Writing: Transform specification tables into Markdown for tools like MkDocs or Docusaurus
• Data Sharing: Share structured data in a format that's easy to read and edit
• Blog Posts: Add comparison tables, pricing tables, or data tables to Markdown-based blogs
