About JSONPath Tester

This JSONPath tester runs a JSONPath expression against a JSON document and returns every node it matches, each labeled with its normalized path. Use it to confirm a query before you paste it into a kubectl command, an Azure CLI script, a Splunk search, or an API response assertion in a test suite.

Key Features

Evaluates child, wildcard and recursive descent operators, including $..author
Supports array index, union, and slice syntax with negative indexes and steps
Filter expressions with ==, !=, <, <=, >, >=, =~ regex, && and ||
Reports the normalized path of every match, so you can address a node directly
Copies matched values as a plain JSON array, or downloads them as a .json file
Parses and evaluates entirely in your browser, so payloads are never uploaded

Use Cases

Test a kubectl -o jsonpath expression before running it against a production cluster
Pull one field out of a 10 MB API response while debugging an integration
Verify the JSONPath an API contract test uses to assert on a checkout response
Check which records match a filter such as [?(@.price < 10)] before shipping a query
Pick apart a CloudFormation or Terraform plan export to find a nested property
Confirm the exact path to a value so you can hard-code it in a monitoring alert

Supported Formats

JSON

.json

.txt

JSONPath (Goessner dialect)

Why does my JSONPath return nothing when the key clearly exists?

The two usual causes are dot notation and filter scope. A key containing a dot, space, or hyphen cannot be reached with $.my-key; it needs bracket notation, $['my-key']. And a filter applies to the members of the collection it is attached to, so $.book[?(@.price < 10)] tests each book, while $[?(@.price < 10)] tests the top-level object itself and matches nothing. Recursive descent, $..price, is the quick way to find where a key actually lives before you write the precise path.
