Complete JSON Toolkit
If you work with APIs, you work with JSON. We have built every JSON utility you will ever need into one place.
JSON Formatter
The JSON Formatter goes beyond basic pretty-printing. Paste any JSON — even minified, escaped or partially broken — and get:
- Syntax-highlighted formatted output
- Collapsible tree view for exploring deeply nested structures
- Real-time error detection with helpful messages
- Minified output mode for production builds
- Character count and size display
All processing happens in your browser. Your API responses and tokens never leave your machine.
JSON Minifier
The JSON Minifier strips all unnecessary whitespace. Useful before embedding JSON in source code or reducing payload size in HTTP responses.
JSON Diff
Debugging why your API response changed between deploys? The JSON Diff tool highlights exactly which keys were added, removed or changed between two JSON objects.
JSON to CSV
Have a JSON array from your database or API? The JSON to CSV converter auto-detects column headers, handles nested objects and generates a downloadable CSV in one click. Supports comma, tab, semicolon and pipe delimiters.
JSONPath Tester
Use the JSONPath Tester to run JSONPath expressions like $.users[?(@.active==true)].name against any JSON. See matching values and their exact paths, with support for filters, wildcards and recursive descent.
JSON Schema Generator
Paste a JSON example into the JSON Schema Generator and get a valid draft-07 schema in seconds. Automatically detects types, formats (email, URI, date-time) and nests required fields.
