JSON Path Finder

What is JSON Path Finder?

JSON Path Finder helps you locate and construct JSONPath expressions for navigating complex JSON documents. Click on any value in a formatted JSON tree view to see the exact JSONPath, JavaScript dot notation, and bracket notation paths to that element. It supports JSONPath syntax including recursive descent (..), wildcards (*), array slices ([start:end]), and filter expressions ([?(@.price < 10)]). The tool also tests expressions against the loaded JSON to show matched values.

API developers extracting data from responses, test engineers writing assertions on JSON payloads, and data engineers building ETL extraction queries. The tool runs entirely in your browser — your data never leaves your device.

How to Use JSON Path Finder

1. Paste a JSON document into the editor to load it as an interactive tree
2. Click on any value in the tree to see its JSONPath, dot notation, and bracket notation
3. Write a JSONPath expression in the query field to find and highlight matching values
4. Test filter expressions to extract values meeting specific conditions

Common Use Cases

• Finding the JSONPath expression to extract specific values from complex API responses
• Building JSONPath queries for data extraction in tools like Postman, jq, or API testing frameworks
• Navigating deeply nested JSON configurations to locate specific settings
• Testing JSONPath filter expressions before using them in production code

Pro Tips

• The recursive descent operator (..) searches all levels — $.store..price finds every 'price' field at any depth, which is useful when you do not know the exact nesting structure
• Array slices use Python-style syntax: $[0:3] gets the first three items, $[-1:] gets the last item, $[::2] gets every other item — these work in most JSONPath implementations
• JSONPath is not standardized (RFC 9535 was published in 2024) — slight syntax differences exist between implementations in JavaScript, Python, Java, and jq; test your expressions in the target language
