Turning JSON Data Into Markdown Tables
JSON is useful for APIs and data exchange, but it is not always easy to read inside GitHub issues, project notes, changelogs, or documentation pages. A Markdown table makes small datasets easier to scan without asking readers to mentally parse brackets and quotes.
This converter takes JSON arrays, objects, and nested records and turns them into copy-ready Markdown tables. It can flatten nested fields, clean headings, handle missing values, and warn when the table may become too wide to read comfortably.

Markdown Tables Work Best With Flat Records
Markdown tables are simple text tables. They work best when each row has flat values such as strings, numbers, booleans, and short labels. Deeply nested JSON can be flattened into dot-path columns, but very wide tables may become difficult to read in GitHub or documentation pages.
Frequently Asked Questions
What JSON formats can this converter read?
It can read arrays of objects, single objects, and objects whose values should be treated as rows. Arrays of objects usually produce the cleanest tables.
Can this flatten nested JSON?
Yes. Use the flatten nested objects option to create columns such as notes.priority or user.email from nested fields.
Can I choose only specific columns?
Yes. Select manual columns and enter a comma-separated list of keys or flattened paths.
Why is my Markdown table too wide?
Wide JSON records can create many columns. Use first-row, common-columns, or manual-columns mode to keep the table readable.
Is anything uploaded while converting JSON to Markdown?
No. The conversion runs entirely inside your browser.
