Tree
The tree appears here as soon as there is valid JSON on the left.
The work
Paste JSON and explore it as a collapsible, colour-coded tree. Search keys and values, copy any path, and switch back to raw text at any time. Runs entirely in your browser.
Paste a document on the left and it becomes a navigable tree on the right, with objects and arrays collapsed past the second level so the overall shape is visible at a glance. Values are coloured by type, and every container shows how many children it holds while collapsed.
The filter box matches both keys and values and automatically opens the branches that contain a hit, which is the fastest way to find one field inside a large API response. Hover any row and click path to copy its full path — ready to paste into your code.
Only the rows currently on screen are rendered, so documents with hundreds of thousands of nodes stay smooth to scroll.
