## What it is
JSONView is a WebExtension for Firefox, Chrome, and Edge that pretty-prints JSON documents in the browser with syntax highlighting and collapsible arrays and objects. It replaces the default download prompt or raw text rendering with a readable, navigable view.

## Use cases
- view json api responses in the browser
- pretty print json in firefox
- collapse and expand json objects in chrome
- read json files without downloading them
- debug rest api responses in the browser
- view malformed json with raw text fallback

## When to choose
- you frequently inspect JSON API responses in Firefox, Chrome, or Edge
- you want collapsible, highlighted JSON rendering instead of a download prompt
- you need copy-paste to remain valid JSON

## When to avoid
- you use Safari, which is not supported
- you need JSON editing or transformation, not just viewing
- you want a standalone JSON viewer outside the browser

- domain: developer-tools, web-development, browser-extensions
- platform: browser, browser-extension, cross-platform
