JSON Viewer

The JSON viewer renders data as a collapsible tree, which makes complex payloads easy to read and is a handy companion for API debugging and config files:

• Tree view: a foldable hierarchy of the whole document
• Expand and collapse: click a node, or expand and collapse everything at once
• Search: find keys or values, highlight matches and jump to the previous or next hit
• Format and minify: switch between pretty and compact output in one click
• Type colors: strings, numbers, booleans and null each get their own color
• Copy path: click a node to copy its JSONPath

When to use it

• Debug deeply nested JSON from a REST API
• Inspect large config files such as package.json or tsconfig.json
• Read query results from Elasticsearch or MongoDB
• Locate a specific field quickly

Everything runs locally in the browser; nothing is uploaded.
