How can I explore large JSON files?

Paste your JSON and use the Tree View to navigate the structure. You can expand/collapse nodes at any depth, and use the depth controls to expand all nodes to a specific level. Click any value to copy it.

Can I search for a value inside my JSON?

Use the JSONPath Tester tool for powerful querying. For example, $.store.book[?(@.price < 10)] finds all books under $10. For simple text searches, use Ctrl+F in the editor view.

What's the difference between Tree View and Table View?

Tree View shows the complete hierarchical structure and is best for nested data. Table View flattens the JSON into rows and columns, which works best for arrays of objects (like API response data).

Can I view JSON from a URL or API?

Currently, paste your JSON directly into the editor. A quick workflow: open your API endpoint in a browser tab, copy the response, then paste it into the JSON Viewer. We're working on direct URL fetching.

Explore deeply nested JSON without scrolling endlessly

Long API payloads, GraphQL responses, and AI tool outputs are hard to read as raw text. A tree view lets you collapse what you don't care about and drill into the parts that matter, so you can find a specific field, count items in an array, or understand the overall shape of an unfamiliar response in seconds.

Use the viewer when you need to

Inspect an unfamiliar API response

Expand and collapse nodes to learn the structure before you wire it into your code or write parsing logic.

Locate a specific field in a large payload

Use the path display and search to jump straight to the value you need without scrolling through thousands of lines.

Switch between tree, table, and raw views

Tree view fits nested data, table view fits arrays of objects, and raw view fits copy-paste — switch as the question changes.

How to view JSON quickly

1
Paste the JSON payload or upload a file.
2
Choose tree view for nested data or table view for arrays of objects.
3
Click any value to copy it, or use the path display to share a pointer to a specific field.

Keep going

Query with JSONPath

Pull specific values out of large payloads using $.path expressions instead of scrolling.

Visualize as a graph

Render the same payload as an interactive node graph when relationships matter more than values.

Find oversized fields

Spot which keys make a payload heavy when network performance matters.

Format raw JSON first

Beautify minified JSON before exploring it for a cleaner reading experience.

Common viewer workflows

Reverse-engineer an undocumented API

Paste a sample response and walk the tree to see what fields exist before writing client code.

Audit a config file

Open the file in tree view to verify nested settings without skimming hundreds of lines.

Share a pointer to a specific value

Copy the dotted path next to a node and paste it into a ticket or message instead of describing it in prose.

常见问题

把 JSON 粘贴进来，用 Tree View 按结构浏览。你可以在任意层级展开/折叠节点，也可以用深度控制一次性展开到指定层级。点击任意值可直接复制。

复杂查询建议用 JSONPath Tester。例如：$.store.book[?(@.price < 10)] 可以找出所有价格低于 10 的书。简单文本搜索则在编辑器里用 Ctrl+F。

Tree View 展示完整的层级结构，更适合嵌套数据；Table View 会把数据“拉平”为行列，更适合对象数组（比如常见的 API response 列表）。

目前需要把 JSON 直接粘贴到编辑器。一个快捷流程是：在浏览器打开 API endpoint，复制响应内容，然后粘贴到 JSON Viewer。我们正在开发直接通过 URL 拉取的功能。
