Free JSON to Markdown Table Converter

How to Convert JSON to a Markdown Table

Paste a JSON array of objects into the left panel and a formatted Markdown table appears on the right. Each object becomes a row, and object keys become column headers. Copy the output directly into your README, wiki, or documentation.

When to Use JSON to Markdown Table

Ideal for documenting API responses in README files, creating comparison tables from data, adding structured data to GitHub issues or pull requests, and generating documentation tables from config files or test results.

Frequently Asked Questions

What Markdown table format is generated?

GitHub-flavored Markdown (GFM) tables with pipe separators and a header separator row. These render correctly on GitHub, GitLab, Bitbucket, and most Markdown renderers.

Does it handle missing keys?

Yes — the tool collects all unique keys across all objects and fills missing values with empty cells.

Are special characters escaped?

Yes — pipe characters (|) in values are escaped so they don't break the table structure. Newlines are replaced with spaces.

Is this converter free?

Yes — completely free, forever. No sign-up, no account, no usage limits.

Is my data safe?

All conversion happens locally in your browser using JavaScript. Your JSON is never uploaded to any server.
