Birdor JSON Lens

A calm, local-first JSON viewer for current pages, pasted snippets, and selected text.

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
