JSON Path Tester: Test JSONPath Expressions Online
Use this JSON Path Tester to evaluate expressions against JSON and inspect every matching value alongside its path. Try dot notation ($.key), array access ([0]), wildcards ([*]), slices ([0:2]), recursive descent ($..key), and basic filters ([?(@.x > 5)]). A syntax cheat-sheet popover helps you check supported patterns and refine queries without first wiring them into your application.
JSON Path Tester is a browser-based tool for evaluating JSONPath expressions against JSON. It shows the values that match your expression and the paths to those values, so you can check what a query selects without first wiring it into an application. Use it to test an expression, explore JSON data, or refine a query before you rely on it elsewhere.
The tester supports dot notation ($.key), array access ([0]), wildcards ([*]), slices ([0:2]), recursive descent ($..key), and basic filters ([?(@.x > 5)]). Enter JSON as the data to query, then provide a JSONPath expression and review the matches. A syntax cheat-sheet popover is available as a reference while you work; the input does not describe additional configurable options.
JSON represents structured data, while JSONPath expressions select values within JSON documents. Converting a selection into a query can help when you need to locate particular fields or array items, explore nested data, or verify that an expression selects the intended values. The tester displays both matches and their paths to make that inspection more informative.
JSON Path Tester runs entirely in your browser: your input is processed on your device and is not uploaded, stored, or sent to a server. Once the page has loaded, it continues to work without a connection. Developers and DevOps engineers can use it to experiment with JSONPath, check real input, and confirm query behavior before shipping.
Step 1: Paste or drop your JSON data into the input area. Use the JSON you want to query, such as a response or configuration object.
Step 2: Enter the JSONPath expression you want to test. You can try dot notation, array access, wildcards, slices, recursive descent, or basic filters.
Step 3: Check the matching values and their paths. Seeing both makes it easier to understand which parts of the JSON your expression selects.
Step 4: Use the syntax cheat-sheet popover if you need a reminder of the supported expression patterns, then adjust your query and review the matches.
Use case: Test a JSONPath expression against real JSON and see exactly which values it matches, along with their paths.
Use case: Refine an expression before wiring it into an application. This lets you iterate without first saving a file or changing app code.
Use case: Check edge cases before shipping a query. Try expressions with array access, wildcards, slices, or basic filters against the JSON you expect to process.
Use case: Inspect a nested JSON response when you need to identify values at particular paths. The matching results help make the expression’s effect easier to see.
Use case: Explore recursive descent when the same key may appear at different levels of a JSON structure. Review the returned values and paths to see what the query selects.
Use case: Use the cheat-sheet popover while learning JSONPath syntax. It provides a convenient reference as you test supported expression patterns.
