JSON to Markdown Table Converter
Convert a JSON array into a Markdown table for READMEs, docs, and GitHub.
All conversions happen in your browser. No data is sent to our servers - see why that matters. Share links encode your input in the URL itself; nothing is stored on a server. Press Cmd/Ctrl + Enter to convert.
How to Convert JSON to a Markdown Table
Paste a JSON array of objects into the input panel. The tool builds a GitHub-flavored Markdown table with a header row from the object keys and one row per item, ready to paste into any README or doc.
Why Markdown Tables?
Markdown is the standard format for developer documentation. Converting JSON data to a Markdown table lets you present API examples, config options, and benchmark results in a readable format directly in your repos.
Common Use Cases
Convert JSON to Markdown when documenting API responses in READMEs, posting structured data in GitHub issues, writing changelogs with data tables, or moving API data into Notion and other Markdown-based tools.
Frequently Asked Questions
Where can I use the generated Markdown table?
Anywhere GitHub-flavored Markdown is supported: GitHub READMEs and issues, GitLab, Notion, Obsidian, Slack posts, Jira, and most documentation generators.
How are pipe characters in data handled?
Pipes (|) inside values are escaped as \| so they don't break the table structure, and newlines inside values are converted to <br> tags.
How are nested objects handled?
Nested objects are flattened into dot-notation columns (e.g., user.name), the same behavior as the JSON to CSV converter.
Is my JSON uploaded anywhere?
No. The conversion runs entirely in your browser - your data never leaves your device.
