JSON Formatter
Format, minify and validate JSON without changing large integers, number notation, key order or string escapes. Import files and locate syntax errors.
JSON Pointer query
Find and extract a JSON value by its path, browse available paths and preserve large numbers exactly.
Updates as you type or change an option
Leave blank for the whole document. Use /users/0/name to select a value; escape / as ~1 and ~ as ~0.
Browse paths (first 300)
About this tool
When an API response is large, select the exact field or array item you need for a test fixture.
How to use
Paste JSON and enter a JSON Pointer such as /users/0/name, or choose a path from the browser. Leave the path empty to select the entire document. Copy the selected value or download it as JSON.
Array indexes start at zero. In property names, escape / as ~1 and ~ as ~0. This tool uses RFC 6901, not JSONPath. Duplicate keys are rejected. Limits: 2 MiB, 30,000 values and 80 nested levels; path browsing shows the first 300 nodes.
Common questions
How do I address keys containing / or ~?
Use ~1 for / and ~0 for ~ within a path segment. Array indexes start at 0; an empty path selects the whole document. JSONPath expressions are not supported.
How do I extract a field that is missing from the path list?
The list shows the first 300 nodes, so type the full path yourself, such as /users/0/id. Index 0 selects the first array item. Extraction preserves the JSON value, including large integers; a missing field produces an error rather than an empty replacement.
