Convert JSON to Markdown Table Online

Turning JSON into a Markdown table is a quick way to show API data where people read text: a GitHub issue, a pull request description, a README, an Obsidian note, or a wiki page that accepts Markdown. Instead of pasting a block of braces, you paste a pipe-delimited table that renders as a grid on GitHub, GitLab and most documentation sites.

Markdown tables work best when they are narrow. JSON records from real APIs often carry 30 or more keys, and a table that wide is unreadable once rendered. Keep only the fields you want with Manage Columns before converting, so the table shows id, title and state rather than every URL and timestamp the API returned. The converter includes the first 1,000 records; for anything longer, a linked CSV file serves readers better.

Cell content is escaped so the table stays valid. A pipe character inside a value becomes \|, and line breaks inside a value become <br>, which GitHub renders as a break inside the cell. Null values leave the cell empty. Nested objects and arrays print as compact JSON text, which gets hard to read in a table, so flatten nested JSON before you publish from it.
