JSON to Markdown Converter

An array of flat objects (like rows from a database or a spreadsheet export) becomes a table. Objects with nested values become a heading for each nested key, with simple values listed as bullets underneath. Arrays of plain values become bullet lists, and a single value is shown on its own.

Nested keys are flattened into dot paths, so {"address": {"city": "Paris"}} becomes a column called address.city. Arrays of plain values are joined with commas, and arrays of objects use their position, such as items.0.name.

It stops the converter from going deeper than the level you choose. Anything below that level is written as compact inline JSON instead of more nested lists or columns. This keeps output readable for deeply nested API responses.

The error message shows the line and column of the problem. The most common causes are a trailing comma after the last item, single quotes instead of double quotes, comments, and missing commas between items. JSON doesn't allow any of these, even though JavaScript does.

Yes. Files up to 25 MB can be uploaded and are converted in your browser. The preview shows the first part of very long output, but Copy and Download always include everything.

No. Parsing and conversion happen in your browser, so API keys or customer data in your JSON never leave your device.
