JSONPath is a query language for JSON, similar to XPath for XML. It allows you to select and extract data from a JSON structure using a path-like syntax. Common implementations are based on the Stefan Goessner's original proposal.
1. Paste your JSON data into the left text area (or load the sample).
2. Enter a JSONPath expression in the input field (starting with $).
3. Click Extract to see matching results. You can also click the example links to try predefined paths.
This tool supports the most common expressions: $ root, .property dot notation, ['property'] bracket notation, * wildcard, .. recursive descent, array indices (e.g., [0]), array slices ([0:2]), and simple filters ([?(@.price < 10)]). It does not cover all edge cases of the official IETF draft.
Absolutely. All processing happens directly in your browser. No data is sent to any server. Your JSON remains private.
Yes, use the .. recursive descent operator. For example, $..author will find all author keys at any level in the JSON tree.
The tool is designed for typical API responses (up to a few MB). Extremely large JSON (tens of MB) may cause performance lag. We recommend formatting your JSON for better readability before extraction.
