Long, deeply nested JSON is hard to read as text. The viewer shows it as a tree: expand only the branches you care about, see the type of every value (string, number, boolean, null, object or array), and copy a value or its path with one click.
Find the field you need without scrolling through thousands of lines.
Understand the shape of a dataset before writing code against it.
Copy the exact path of a nested value to use in code.
A tree of your JSON with every key, its value and its type. Objects and arrays can be expanded or collapsed, and arrays show how many items they contain.
