JSON Formatter
Format, validate, minify, search, and explore JSON in code, form, text, tree, and preview views.
Format/Validate
Tool overview
JSON Formatter helps you validate, beautify, minify, search, and inspect JSON directly in your browser. Use the side-by-side editor for quick corrections, then switch to a tree or form view when you need to understand the data structure.
What you can do
- Validate JSON syntax and identify the reported error line.
- Beautify JSON with two, three, or four spaces of indentation.
- Minify payloads for compact storage or request testing.
- Explore objects and arrays in code, form, text, tree, and view modes.
Working with JSON safely
JSON is a text format for objects, arrays, strings, numbers, booleans, and null values. Property names and string values must use double quotes, and comments are not part of standard JSON.
The formatter processes entered data in the browser. Still, avoid placing credentials, access tokens, or other sensitive information into any online tool unless your own security policy permits it.
