Convert a JSON array into a GitHub-ready Markdown table
Runs 100% in your browser — nothing is ever uploaded.
What is JSON to Markdown?
Convert any JSON array of objects into a neatly aligned Markdown table: column widths are padded for readable source, pipe characters are escaped, and the result renders perfectly on GitHub, GitLab, Notion and most wikis.
How to use JSON to Markdown
- Paste your JSON array into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (delimiter, table name, format …).
- Click the convert button — the Markdown table appears instantly in the output pane.
- Copy the result with one click or download it as a file.
