Explore large or deeply nested JSON as a collapsible tree, with type indicators and the path to any node, instead of scrolling through thousands of indented lines.
Paste JSON to explore it as an interactive tree. Click values to copy, search to find keys or values, and expand/collapse sections.
This is the tool for an unfamiliar API response. A formatted 3,000-line payload is technically readable and practically not; a collapsible tree lets you close everything, expand the one branch you care about, and see the shape at each level. The path display then gives you the exact accessor to write.
Type indicators matter more than they sound. JSON distinguishes the number 0, the string 0, false, null, and an absent key, and code that treats them interchangeably breaks in ways that are hard to trace. Seeing types explicitly makes that class of bug visible before you write against the payload.
