JSON Tree View
12 toolsBrowse JSON as a collapsible tree.
Runs in your browser — your files and text stay on your device
Everything you'd need a dedicated JSON app for — formatting, a collapsible tree view, structural diffing, converting to/from CSV, YAML, and XML, generating TypeScript interfaces and JSON Schemas, querying with JSONPath, and validating JSON Lines — runs entirely client-side using your browser's native JSON engine, so nothing you paste is ever sent to a server.

Frequently asked questions
Why use a tree view instead of the formatted text output?
Large or deeply nested JSON becomes hard to scan as flat text — a collapsible tree lets you fold away sections you don't need and focus on the part you're debugging.
Is my JSON uploaded anywhere?
No, the tree is rendered entirely in your browser.
