AZ JSON Explorer

View, format, search, and browse large JSON. Parse nested JSON strings into expandable trees with one click.

AZ JSON Explorer is a local-first JSON viewer for developers working with API responses, logs, fixtures, and local files. It is built around three focused workflows: Key features: - Parse as JSON: turn escaped objects or arrays into browsable tree nodes, while preserving the original string so you can switch between raw and parsed views. - Isolated views: open any object, array, or JSON string in its own tab. Each tab keeps its own raw/parsed mode and search state. - History: reopen successfully parsed manual inputs and files from local history, together with restored tabs and per-tab view state. AZ JSON Explorer can replace raw JSON pages directly in Chrome or open manual input and local files in its standalone viewer. Web Worker parsing and virtual scrolling keep large trees responsive. The interface is available in English and Simplified Chinese and follows Chrome's UI language automatically. History is stored locally in your browser until you clean it. JSON content is never uploaded or synced to an external server. Like AZ JSON Explorer?
