FAQ
JSON Tree Viewer — Frequently Asked Questions
JSON tree structure, click-to-copy JSONPath, and large-payload behavior — explained.
What is a JSON tree viewer and why use one?
A JSON tree viewer renders the JSON tree structure as collapsible nodes so you can navigate deeply nested data without scrolling through thousands of lines. It is the fastest way to read large API responses, inspect configs, or audit a payload.
How does click-to-copy JSONPath work?
Click any key, value, or array index in the JSON viewer. We compute the JSONPath (e.g.
$.users[3].email) and copy it to your clipboard — drop it into the JSONPath Tester or paste it into your code.Can I expand or collapse all nodes at once?
Yes — Expand all and Collapse all buttons live in the output toolbar. Click the caret on any node to toggle just that subtree. Useful when comparing a large payload to a small reference shape.
Is the JSON tree viewer linked with the JSONPath tester?
Yes. Switch to the JSONPath tab and matched nodes light up in the tree. Click a node and the JSONPath fills the query box automatically — round-trip exploration without copy/paste.
Is my JSON data sent anywhere?
No. The JSON viewer renders the tree in your browser only. We have no servers, no logs of your data, and no behavioural analytics on your JSON — your data never leaves the page.
Can the JSON viewer handle large or deeply nested payloads?
Yes. The tree is virtualized and lazy-rendered — collapsed branches are not parsed into DOM until expanded, so even multi-megabyte JSON documents stay responsive.
