Frequently Asked Questions
- What are JSON paths?
- JSON paths use dot notation to describe the location of a value within the data structure. For example, $.user.address.city refers to the city field inside the address object inside the user object.
What is JSON Viewer?
A JSON viewer provides a detailed structural analysis of JSON data, displaying every path from root to leaf nodes with the corresponding value and data type. Unlike a simple formatter that only adds indentation, a viewer deconstructs the JSON into a flat path representation (like $.users[0].name) that makes it easy to identify specific values within deeply nested structures. This is invaluable for understanding complex API responses, navigating large configuration objects, and building queries or transformations that target specific data paths. The viewer shows object key counts, array lengths, value types (string, number, boolean, null), and the full dot-notation path to every element.
