Question 1

What does a JSON viewer do?

Accepted Answer

A JSON viewer renders raw JSON as an interactive collapsible tree, making it easy to navigate nested structures, identify data types, and explore large JSON documents without reading compressed text.

Question 2

How do I navigate large JSON with a tree viewer?

Accepted Answer

Click any object or array node to collapse it and hide its children, reducing visual clutter. Use Expand All to open every node at once or Collapse All to fold the entire tree back to the root level.

Question 3

What is JSON path notation?

Accepted Answer

JSON path notation uses $ to represent the root and dot notation for keys (e.g. $.user.name) or bracket notation for arrays (e.g. $.roles[0]). It uniquely identifies any value within a JSON document.

Question 4

How do I use a JSON viewer with API responses?

Accepted Answer

Copy the raw JSON body from your browser's DevTools Network tab or from Postman and paste it into the viewer. The tree immediately shows the full structure, data types, and values of the response.

Question 5

How is a JSON viewer different from browser DevTools?

Accepted Answer

Browser DevTools show JSON only for live network requests. This standalone viewer lets you paste any JSON — from files, logs, clipboard, or a text editor — and explore it as a tree with path copying and expand/collapse controls.
