Test filters, wildcards, recursive descent, and array slicing — all in your browser with no installation required. Includes built-in examples and a complete JSONPath syntax reference. **Use this tool:** [JSON Path Finder](https://findutils.com/developers/json-path-finder/) ## Programmatic access - REST id `json-path-finder`: POST https://api.findutils.com/api/tools/json-path-finder/execute (reference: https://findutils.com/api/json-path-finder/) - MCP tool `json_path_finder` on https://mcp.findutils.com (reference: https://findutils.com/mcp/json-path-finder/) ## Why Use JSON Path Finder? Working with deeply nested JSON structures means manually tracing through layers of objects and arrays to find the right path. One wrong key name or missed array index and your query returns nothing. JSON Path Finder lets you paste any JSON document, click on a value in the interactive tree, and instantly get the exact JSONPath expression to access it. Test expressions against your data in real time, use advanced filters and array slicing, and copy paths ready to paste into your code. Supports both dot notation and bracket notation. ## Pro Tips - Start with $ and build incrementally — add one level of depth at a time to understand the structure before writing complex expressions. - Use $.fieldName (recursive descent) when you know the key name but not its exact location in the hierarchy. - Combine filters with wildcards for powerful queries: $.users[?(@.age>30)].name returns only the names of users over 30. - Click any path chip in the results to copy the full resolved path — paste it directly into your code or test assertions. - Load the built-in sample data to practice with a realistic nested structure before working with your own JSON. ## Frequently Asked Questions ### What is JSONPath? JSONPath is a query language for JSON, similar to XPath for XML. It allows you to specify paths to elements within a JSON document using dot notation, brackets, wildcards, and filter expressions. Starting from the root ($), you build expressions to navigate to exactly the data you need. ### How do I copy a matched path? When your JSONPath expression returns results, the matched paths are shown as clickable chips above the output. Click any path chip to copy it to your clipboard instantly. ### What JSONPath features are supported? This tool supports property access ($.field), bracket notation ($['key']), array indexing ($[0], $[-1]), array slicing ($[0:3]), wildcards ($[*]), recursive descent ($.field), and filter expressions ($[?(@.age>25)]). ### What JSON types are shown? The tool handles all JSON types: objects, arrays, strings, numbers, booleans, and null values. Results are displayed as formatted JSON with syntax highlighting. ### Can I use this with API responses? Yes! Copy the JSON response from your API testing tool, browser dev tools, or Postman and paste it into the input panel. Use JSONPath expressions to quickly extract the specific data you need. ### Does the JSON Path Finder require a signup, and is it private? No signup. This JSON Path Finder is available with no account required. All processing happens entirely in your browser — your JSON data is never sent to any server. ### What is the difference between JSONPath and jq? JSONPath is a query/selection language for extracting values from JSON (like XPath for XML). jq is a full programming language that can select, transform, aggregate, and construct new JSON structures. Use JSONPath for simple extraction; use jq for data transformation. ### How do I filter array elements? Use filter expressions with the @ symbol: $.users[?(@.age>25)] returns users older than 25, $.items[?(@.active==true)] returns active items, and $.products[?(@.price<=100)] returns products costing 100 or less. ### Can I use recursive descent to find deeply nested keys? Yes. The recursive descent operator (.) searches at every depth. For example, $.email finds all "email" values no matter how deeply nested they are. This is one of the most powerful JSONPath features for exploring unfamiliar data structures. ### Does this tool support array slicing? Yes. Array slicing uses the syntax $[start:end:step]. For example, $.items[0:5] returns the first five elements, $.items[-3:] returns the last three, and $.items[::2] returns every other element. Negative indices count from the end of the array. ## Related Tools - [JSON Formatter](https://findutils.com/developers/json-formatter/) - [JSON Visualizer](https://findutils.com/developers/json-visualizer/) - [JQ Playground](https://findutils.com/developers/jq-playground/) - [JSON Diff](https://findutils.com/developers/json-diff/) - [JSON Schema Validator](https://findutils.com/developers/json-schema-validator/) - [JSON to TypeScript](https://findutils.com/developers/json-to-typescript/) - [JSON Faker](https://findutils.com/developers/json-faker/) - [JSON Comparer](https://findutils.com/developers/json-comparer/)
