Convert JSON to Markdown.
Drop a .json file and get readable, pretty-printed Markdown in seconds. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files

Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Data, made
readable.
Minified JSON is dense and hard to scan. Converting parses it and pretty-prints every key and value inside a fenced block, so it reads cleanly in notes, docs and prompts.
{"name":"Ada","tags":["x","y"]}
Everything sits on a single line, hard to scan and hard to diff.
```json
{
"name": "Ada",
"tags": [
"x",
"y"
]
}
```
Everything you
actually need.
JSON in, readable Markdown out, with no server and no account anywhere.
It never leaves your browser
The .json file is read and converted on your own device. Nothing is uploaded to any server, ever.
# Heading

AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
{"id":1,"ok":true}
"id": 1,
"ok": true
Lossless & pretty-printed
Every key, value and nested level is kept, then indented across lines so it reads.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
What survives
the trip.
JSON conversion is lossless: nothing is dropped. Every key and value survives; the only changes are cosmetic. These are the same notes the Formats list shows for JSON.
Kept
4- Every key and value
- Nested structure
- Arrays and objects
- Invalid JSON, verbatim
Reformatted
4- Pretty-printed
- Wrapped in a code fence
- OpenAPI summarized
- Spacing normalized
"name": "Ada",
"count": 3,
"active": true
"tags": [
"x", "y"
]
JSON questions,
answered.
Everything worth knowing before you drop in a .json file.
