Privacy: The JSON stays in your browser. Nothing is uploaded.

## About

Paste any JSON and explore it as a collapsible tree. Each key, value, and array element is a node you can click to expand or copy.

The viewer shows the JSON Pointer path of every value (for example /users/0/name) and a one-line summary of the node. Click a primitive to copy its value; click a container to toggle its children. Useful for understanding API responses, debugging large config files, and finding the right path to copy into a script.

## How to use

1. **Paste your JSON** — Drop a file or paste text into the editor on the left.
2. **Explore the tree** — Click any node to expand or collapse its children. Use Expand all / Collapse all for big trees.
3. **Copy values or paths** — Click a primitive value to copy it. The path (for example /data/users/2/email) is shown next to each node and is one click to copy.

## Examples

### API response navigation

Most API responses are deeply nested. The tree view lets you collapse everything except the section you are looking at, then drill in.

Input:

```
{ "data": { "users": [ { "id": 1, "name": "alice" }, { "id": 2, "name": "bob" } ] } }
```

Output:

```
A collapsible tree where /data/users/0/name resolves to "alice".
```

### Config file debugging

Long package.json, tsconfig.json, or .eslintrc files are easier to read as a tree than as flat text.

Input:

```
{ "name": "app", "scripts": { "build": "vite build", "test": "vitest" } }
```

Output:

```
Each script is a clickable leaf; click to copy the script name.
```

## FAQ

### Is my JSON uploaded anywhere?

No. The viewer runs entirely in your browser. The text you paste never leaves your device, and there is no server-side parsing or storage.

### What is the "path" next to each node?

It is a JSON Pointer (RFC 6901). For example, /users/0/name refers to the name field of the first user. Most JSON tools and the $.. selector in tools like jq use the same syntax.

### How big a JSON can I paste?

The viewer handles JSON up to a few megabytes comfortably — large enough for any realistic API response or config file. If the JSON is many megabytes, the browser may slow down; the viewer shows how many nodes it found so you can tell when a file is too big to comfortably browse.

### What if my JSON is invalid?

The viewer shows the exact error from the parser — line and column number, plus the character position — so you can fix the syntax issue. Use the JSON Validator tool for a more detailed error breakdown.
