JSON to Markdown table
Paste a JSON array of objects — or a whole API response: the first array of objects inside it is used. Each object becomes a row; nested objects become columns like address.city. Nothing is uploaded — the conversion runs in this page.
Frequently asked questions
Where can I use the Markdown table?
READMEs, GitHub/GitLab issues and PRs, Obsidian, docs sites and LLM prompts all accept GitHub-flavored Markdown tables.
How are nested objects and arrays handled?
Nested objects flatten to dot-notation columns; arrays of plain values are joined with “; ”; arrays of objects stay as JSON text in one cell.
Can I get CSV or Excel instead?
Yes — switch the format to CSV or TSV, or download .xlsx.
Is my data sent to a server?
No. The page has no analytics and makes no network requests with your input.
