Description

Open an application/json endpoint in a tab and JSON Lens instantly turns it into an interactive, collapsible tree. Search any key or value, evaluate basic JSONPath expressions (e.g. $.users[0].name) and copy paths with a click. Everything runs in the browser: no data ever leaves your machine.

Features

  • Automatically detects application/json responses opened in a tab (via content-type or body parsing)
  • Navigable tree with native collapse/expand for nested objects and arrays
  • Instant full-text search over keys, values and paths
  • Basic JSONPath evaluator: $, .key, ['key'], [index]
  • One-click copy of each node's JSONPath
  • Safe degradation: never touches pages that aren't raw JSON
  • 100% offline, no telemetry, no data sent anywhere

Privacy

100% local processing in your browser. Zero telemetry: no data is sent to external servers.

Required permissions

  • host_permissions: <all_urls>
