What is a JSON parser and tree viewer?
A JSON parser reads text into a data structure; a tree viewer shows that structure as an expandable outline so you can navigate deep payloads without scrolling through thousands of lines.
It is the fastest way to answer "what is actually inside this response?" — expand one branch, check the shape of an array, and confirm a field name without eyeballing raw text.
How to parse and explore JSON
- Paste the payload into the editor.
- Switch to the Tree tab to see the parsed structure.
- Expand or collapse nodes to walk into objects and arrays.
- Click a node to highlight its path and value in the pane.
- Use the status bar to check the node count and depth of the document.
Tree view examples
Collapsed root
{"orders":[{"id":1},{"id":2}]}root {1}
└─ orders [2]
├─ {0} {1}
└─ {1} {1}Expanded item
{"orders":[{"id":1,"total":9.5}]}orders[0].id = 1 orders[0].total = 9.5
Tree viewer vs raw text
| Dimension | Tree viewer | Raw text editor |
|---|---|---|
| Deep payloads | Navigate by expanding nodes | Scroll and match brackets |
| Shape overview | Structure visible at a glance | Only indentation |
| Editing | Read-only view | Full editing |
| Large files | Best for inspection | Best for editing |
FAQ
Frequently Asked Questions & Specs
Can I view very large JSON?
Yes, rendering is virtualised per node and stays in the browser, so there is no upload limit.
Is my JSON sent anywhere?
No. Parsing and rendering happen entirely on your device.

- Expand and collapse nodes to inspect deep structures without losing context.
- The tree is generated from valid JSON only — fix syntax errors first.
