1. Extracting Authors from a Bookstore API
Backend DeveloperBackground
A developer is testing a bookstore API and receives a deeply nested JSON response containing various book details.
Problem
They need to quickly extract just the list of author names without manually parsing the entire JSON tree.
How to use
Paste the JSON response, enter the expression `$.store.book[*].author`, and check 'Save Query Template' to reuse it later.
{
"expression": "$.store.book[*].author",
"outputFormat": "json",
"maxMatches": 20,
"saveTemplate": true,
"templateName": "Book authors"
}Outcome
The tool extracts all author names into a clean JSON array and saves the query as a reusable template.
