JSON Formatter and Validator

Paste minified or broken JSON and get it back indented. ParseBox shows the line of a syntax error, and it repairs common mistakes such as trailing commas, single quotes and missing quotes around keys.

Example

Input
{"name":"parsebox","tags":["json","yaml",],"nested":{"ok":true,"count":3},}
Output
{
  "name": "parsebox",
  "tags": [
    "json",
    "yaml"
  ],
  "nested": {
    "ok": true,
    "count": 3
  }
}

Private by design

ParseBox runs entirely in your browser. Your text is never uploaded, logged or stored on a server, so it is safe to paste API responses, tokens and config files.
