What is JSON Path Tester?
JSONPath is a query language for JSON, similar to XPath for XML.
It lets you navigate and extract specific values from complex JSON structures using expressions like $.store.book[0].title (first book title) or $..author (all authors at any depth). This tool evaluates JSONPath expressions against your JSON data entirely in the browser, showing matched results instantly.
How to use JSON Path Tester
- 1
Enter your JSON
Paste or type your JSON data in the left panel. The tool validates JSON syntax in real-time and highlights errors. Click "Try Example" to load sample data.
- 2
Write a JSONPath expression
Enter a JSONPath expression in the top input field. All expressions start with $ (the root). Use dot notation for properties ($.store), brackets for arrays ($.book[0]), and two dots for recursive descent ($..price).
- 3
Click Run
Press the Run button or hit Enter. The tool evaluates the expression against your JSON and shows all matching values in the right panel.
- 4
Review matches
Each match is displayed with its index, type, and value. Objects and arrays are formatted as pretty-printed JSON. Click Copy to get all results as a JSON array.
- 5
Try example paths
Click the example path buttons below the input to quickly test common patterns. Each button fills in a different JSONPath expression.
