Convert JSON files to readable Markdown
Open a local JSON file and turn it into a titled Markdown document with a pretty-printed, fenced code block.
Parsing and formatting run in the browser so API dumps, config files, and export payloads stay on the device.
Or drop a file on this page. It stays in this browser.
Local browser processing. No document upload.

JSON
- 1Choose a .json file.
- 2Markdown Lens validates and pretty-prints it locally.
- 3Copy or export the fenced Markdown.
What the converter preserves
- Valid JSON structure
- Pretty-printed indentation
- Unicode text
- A document title from the filename
Limitations to review
Markdown represents document structure, not every visual layout detail.
- Invalid JSON is rejected rather than repaired.
- Markdown does not execute or query the data.
- Very large payloads may be easier to inspect in a dedicated JSON viewer.
Questions about JSON
Is JSON uploaded?
No. The file is parsed and formatted in the browser.
Does it convert JSON into tables automatically?
No. This release pretty-prints JSON as a fenced code block so nested structures stay intact.
