Frequently Asked Questions

Is my JSON data sent to a server?

No. All processing happens locally in your browser using JavaScript. Your JSON never leaves your device - this is a privacy-first tool.

What is a JSON path?

A JSON path is a dot-notation string that identifies the location of a value within the structure. For example, "users.0.name" points to the name of the first user in a users array.

How do I search within the JSON?

Type any keyword in the search bar and the tree will filter to show only matching nodes. Matching keys and values are highlighted. Clear the search to restore the full tree.

Can I copy a specific value?

Yes. Hover over any node and click the copy button that appears next to it. You can copy the JSON path, the raw value, or the entire subtree as formatted JSON.

What does "collapse to depth" mean?

"Collapse to depth N" collapses all nodes deeper than N levels. For example, depth 2 shows the root and its direct children, but hides grandchildren. This helps you focus on the high-level structure.

What file formats are supported?

You can paste raw JSON text, upload .json files, or drag & drop .json files. The tool also accepts clipboard content from copied JSON.

Does it handle large JSON files?

Yes. The visualizer uses a virtualized rendering approach and can handle JSON structures with thousands of nodes. Performance depends on your browser's JavaScript engine.
