Simple Process

How to Convert JSON to Markdown

1

Drop a .json file

Drag one or more .json files onto the converter at the top of the page, or click it to choose files.

2

Let it format the JSON

Valid JSON is parsed and pretty-printed with two-space indentation inside a json code block, in your browser.

3

Download the .md file

Download the Markdown file, or several at once as a ZIP, and paste the block into your README, docs or notes.

What gets converted

This converter does one job: it turns a JSON file into a Markdown file that displays the JSON well. It does not turn your data into headings, lists or tables. Here is exactly what happens, checked against the converter code.

JSON input Converted? Markdown output
Valid JSON of any shape Yes Pretty-printed with two-space indentation inside a ```json fenced code block
Minified, one-line JSON Yes Expanded onto multiple lines
Nested objects and arrays Yes Indented two spaces per level
Key order Yes Kept as in the file
Unicode escapes such as é Yes Written as the character itself (é)
Numbers such as 1.0 or 1e3 Partial Rewritten in their shortest form (1, 1000)
Integers above 9,007,199,254,740,991 Partial Rounded, because JavaScript numbers lose precision past that point
Duplicate keys in one object Partial Only the last value is kept
Keys named __proto__, constructor or prototype No Dropped while parsing, for safety
Invalid JSON, JSON with comments or trailing commas No formatting Wrapped in a json code block exactly as written
Arrays of records No table Kept as JSON. For a table, see the CSV tip below.

The JSON is only reformatted when it parses, so a file that comes out unchanged is a sign it isn't valid JSON.

Use Cases

Common JSON Conversion Use Cases

API documentation

Drop a saved API response and get a ready-made example block for OpenAPI docs, developer guides, and API references.

Configuration file docs

Document a JSON config file alongside prose that explains each setting. The code block keeps the file exact.

Issue reports and pull requests

Attach a formatted JSON payload to a GitHub issue or PR description without the indentation getting mangled.

Developer notes

Keep sample payloads and fixtures as .md notes in Obsidian or a docs repo, where they render with highlighting.

Common problems and fixes

My JSON came out exactly as it went in

The file didn't parse as JSON. The usual causes are comments (// or /* */), a trailing comma after the last item, single quotes instead of double quotes, or JSON Lines (one object per line). Fix the file in an editor that flags JSON errors, such as VS Code, then convert it again. Rather than guess, the converter keeps your text untouched.

A long ID number changed

JavaScript stores numbers as 64-bit floating point, so integers longer than about 16 digits are rounded when the file is parsed. If your data has large numeric IDs, store them as strings ("id": "12345678901234567890") or skip the reformatting by pasting the original text into a code block by hand.

Pasting JSON didn't give me a code block

The paste box is built for rich text from documents and web pages, so pasted JSON is treated as plain text. Save the JSON as a .json file and drop the file instead. Or type three backticks and json on the line above your JSON, and three backticks on the line below. That is all a fenced code block is.

I wanted a Markdown table

JSON nests, and Markdown tables can't. If your JSON is a flat array of records, export it to CSV (in a spreadsheet, a script, or a tool like jq) and drop the CSV on the CSV to Markdown converter, or paste it into the Markdown table generator.

Other ways to put JSON in Markdown

  • By hand. A fenced code block is three backticks plus json, your JSON, and three closing backticks. Format the JSON first with your editor's Format Document command.
  • jq. The command-line JSON processor pretty-prints with jq . data.json, and can also reshape records into CSV for a table.
  • Python. json.dumps(data, indent=2) produces the same two-space formatting in a script.
  • Pandoc. Pandoc's json input is its own document format, not arbitrary JSON, so it isn't a general JSON converter.

Use this page when you want the formatted block and the .md file in one step, without installing anything and without your data leaving your computer.
