JSON to Markdown Converter

Convert

Turn JSON into Markdown tables and lists ready for READMEs, docs, and GitHub.

Convert JSON to a Markdown table

When you need to drop data into a README, a wiki page, a pull request, or a Notion doc, Markdown is the answer. This converter turns a JSON array of objects into a GitHub-flavored Markdown (GFM) table — keys become column headers, each object becomes a row — and renders deeply nested or mixed data as clean, indented bullet lists instead.

Auto, table, or list output

Let the tool pick the best shape automatically, or force a table or a list when you know what you want. Pipes and line breaks inside values are escaped so your tables never break mid-render, and the output is standard GFM that renders correctly on GitHub, GitLab, Notion, Obsidian, and most other Markdown engines.

To see exactly how the result will look, paste it into the Markdown viewer, which renders GitHub-flavored tables and lists the way GitHub displays them.

Documentation tools speak Markdown, not JSON. Convert JSON to a Markdown table online and paste the result straight into a README, a GitHub issue or pull request, a wiki, or a Notion page. An array of objects becomes a clean GFM table; deeply nested data becomes an indented bullet list — both render correctly anywhere Markdown is supported.
