  description

  Birdor JSON Lens is a calm, local-first JSON viewer for developers. It focuses
  on reading, searching, and copying paths from JSON responses, not replacing API
  clients or developer tools.
  
  ## Key Features
  
  - Render JSON URLs from `<pre>` or `document.body.innerText`.
  - Open a local JSON Scratchpad from the popup.
  - Paste JSON snippets and validate, format, or minify them locally.
  - Right-click selected text on any webpage to view, validate, or format it as JSON.
  - Tree / Pretty / Raw views.
  - Collapsible object and array nodes with `Object(n)` and `Array(n)`.
  - Search keys, values, and paths with highlighted matches.
  - Search automatically expands matched parent paths.
  - Search result list with clickable jumps back into the tree.
  - Top-level JSON outline for quick navigation across root keys or array items.
  - Copy value, key, dot path, JSONPath, subtree, or full JSON.
  - Copy Pretty, Minified, or Raw JSON from Scratchpad.
  - Collapse All and Expand 1 Level controls.
  - Dot path and JSONPath handle arrays and special keys.
  - Smart hints for timestamps, ISO dates, HTTP/HTTPS URLs, JWTs, UUIDs, and colors.
  - Show more for large arrays without rendering every item at once.
  - Jump to index for large arrays.
  - Safe Mode for large JSON, backed by local JSON stats estimation.
  - Search result jumps work with partially rendered arrays.
  - Outline item counts are capped for large JSON.
  - Dark mode with system, light, and dark themes.
  - Local settings saved with `chrome.storage.sync`.
  - Local-first.
  - No upload.
  - No tracking.
  - No account.

  Birdor JSON Lens makes JSON readable wherever you find it - current-page JSON, pasted snippets, selected text, local JSON files, config snippets, and structured logs.
  
  Open a JSON response, click Render current page, or paste a snippet into the local scratchpad, then view it as a clean, searchable, collapsible tree. Compare two pasted JSON documents locally, recognize common document shapes, diagnose invalid JSON, preview escaped JSON strings, and copy values, keys, dot paths, JSONPath, jq paths, lodash paths, subtrees, Pretty JSON, Minified JSON, or Raw JSON in one click.
  
  Built for developers who frequently inspect API responses, copied config snippets, manifests, and structured logs.
  
  Highlights:
  - Render the current JSON page after a user click
  - Paste JSON into a local scratchpad
  - View selected text as JSON
  - Drop a local .json file into the Scratchpad
  - Validate and format JSON locally
  - Compare two pasted JSON documents locally
  - Recognize OpenAPI, JSON Schema, package.json, and tsconfig shapes with local navigation summaries
  - Diagnose common invalid JSON patterns without silently rewriting input
  - Preview nested escaped JSON strings
  - Tree / Pretty / Raw views
  - Search keys, values, and paths
  - Copy value, key, dot path, JSONPath, jq path, lodash path, and subtree
  - Copy Pretty, Minified, or Raw JSON
  - Smart hints for timestamps, URLs, JWTs, UUIDs, and colors
  - Large JSON safe mode with progressive array, object, search, and diff workflows
  - Dark mode
  - Local-first: no upload, no tracking, no account
