Kiểm tra JSONPath

JSONPath lets you reach into nested JSON values the way XPath does for XML — a compact path string like $.users[0].email instead of manually walking the structure. This tool lets you test an expression against real data and see the result instantly.

How to use it

• Paste JSON data into one field and a JSONPath expression into the other.
• The result shows every matched value along with its exact path, even when there are several matches.
• Use [*] to iterate over every array element, or a filter like [?(@.price > 100)] for conditional selection.

Common uses

• Working out the right JSONPath expression to pull a specific field from an API response before pasting it into code.
• Testing data-transformation or message-routing rules that rely on JSONPath (for example, in AWS Step Functions or an API Gateway).
• Quickly locating a value in a large, deeply nested JSON document without scrolling through it manually.

Things to keep in mind

There's no single official JSONPath standard — the basic syntax (dots, brackets, *) is supported the same way everywhere, but filters and more advanced expressions differ between libraries.

Array indexing in JSONPath starts at zero, like in most programming languages — [0] means the first element.
