JSON Formatter
Paste JSON, then beautify it for reading or minify it for compact payloads. Formatting happens locally and nothing is stored.
This tool runs entirely in your browser. Your JSON is not sent to DNVERSE servers.
Format JSON in your browser
This JSON Formatter online indents objects and arrays so you can read them, and minifies the same document when you need a smaller payload. Use Beautify as a JSON beautifier and pretty print view; Minify is the compact form. Invalid JSON is reported immediately so you can fix it before copying.
How to format JSON
- Paste JSON into the input area or load the example.
- Choose Beautify to pretty print the document, or Minify to compact it.
- Copy the result when you need it in an editor or API client.
JSON Formatter FAQ
Does DNVERSE upload my JSON?
No. JSON is formatted in your browser. DNVERSE may record anonymized usage counts without the document contents.
What if my JSON is invalid?
The formatter shows a parse error with the position so you can fix the document first. For a syntax-only check, use the JSON Validator.
Is this a JSON beautifier and pretty printer?
Yes. Beautify pretty prints with indentation. Minify removes extra whitespace. Both run locally as a JSON formatter, not as a schema checker.
