Format & Beautify
Format, beautify, and minify JSON data — all locally in your browser.
JSON Editor
Edit, validate, format, and minify JSON online in your browser. Paste or open a JSON file, make changes in a syntax-highlighted editor, and copy or download the result without an account.
JSON Escape & Unescape
Escape raw text or JSON content into a JSON-safe string and unescape JSON string literals back to readable text. Handle quotes, backslashes, line breaks, tabs, control characters, and Unicode escapes directly in your browser.
JSON Minifier
Minify valid JSON by removing insignificant whitespace between JSON tokens. Create compact, single-line output without changing parsed values or structure, compare character and byte sizes, and copy or download the result directly in your browser.
JSONPath Tester
Evaluate JSONPath expressions against JSON data in your browser. Query nested objects and arrays, test selectors, inspect matching values and paths, and copy the results for API debugging, configuration work, and data-processing tasks.
JSON Repair
Repair broken or invalid JSON in your browser. Fix trailing commas, single quotes, unquoted keys, missing brackets, comments, and Python constants, then copy or download valid JSON without uploading your data.
JSON Schema Validator
Validate JSON data against a JSON Schema. This online JSON Schema validator lets you validate JSON against schema, check structure, data types, required fields, and constraints, and get detailed error messages — all in your browser.
