Questions
What is JSONPath?
JSONPath is a query language for JSON, similar to XPath for XML. It lets you extract specific values from complex JSON structures using expressions like $.store.book[0].title.
What JSONPath syntax is supported?
Standard JSONPath syntax including dot notation ($.key), bracket notation ($["key"]), wildcards (*), array slicing ([0:2]), and filter expressions ([?(@.price < 10)]).
How do I select all items in a JSON array?
Use $.arrayName[*] to select all elements, or $.arrayName[*].fieldName to extract a specific field from every object in the array.
JSONPath vs jq: what is the difference?
JSONPath is a query language used in many programming libraries, while jq is a standalone command-line tool with its own syntax. Both extract data from JSON but jq is more powerful for transformations.
How do I filter JSON array items by a property value?
Use a filter expression like $.items[?(@.status=="active")] to select only array elements where the status field equals "active". Filter expressions support comparison operators and logical AND/OR.
Does the JSONPath tester work offline?
Yes, the JSONPath evaluation runs entirely in your browser. Your JSON data and queries never leave your device.
