Convert JSON to Markdown
Paste your JSON and we will format it as a prettified Markdown code block. Great for including API responses, configuration, or structured data in your Markdown documentation.
About this tool
What this converter does
JSON copied from logs, API responses, or network inspectors usually arrives minified: one endless line that no reader can follow. This tool validates the JSON, pretty-prints it with two-space indentation, and wraps it in a fenced json code block ready to paste into documentation.
Because parsing happens before formatting, it doubles as a quick validity check: malformed JSON is rejected with an error instead of producing a broken code block. Everything runs in your browser, so response payloads never leave your machine.
How to use JSON to Markdown
- 1
Paste the JSON
Minified or already formatted, from an API response, a log line, or a configuration file.
- 2
Validate and pretty-print
The input is parsed to confirm it is valid JSON, then reprinted with consistent two-space indentation inside a fenced block.
- 3
Drop it into your docs
Copy the fenced block into API documentation, a README, or an issue, where it renders with syntax highlighting.
Good to know
- Invalid JSON is rejected with an error, which makes the tool a fast sanity check for hand-edited payloads.
- Object keys keep their original order; the formatter changes whitespace, never content.
- Parsing and formatting run client-side, with no upload involved.
FAQs
Common questions
My input fails with an invalid JSON error. What now?
The usual culprits are trailing commas, single quotes instead of double quotes, and unquoted keys, none of which strict JSON allows. Fix those and the formatter will accept it.
Does formatting change my data?
No. The payload is parsed and re-serialized with indentation only; keys, values, and their order are exactly what you pasted.
Can I format JSON with sensitive values in it?
The conversion happens in your browser and nothing is uploaded, so the data stays on your machine. Still, redact secrets before publishing the formatted block anywhere public.
