Show HN: JSON Viewer Extension for Chrome
A Chrome extension named JSON Viewer Formatter allows users to view and format JSON data directly in the browser. It provides a clean, tree-based layout for easier reading and navigation of JSON responses. The tool is designed for developers working with APIs or JSON files.
Background
The linked page is a Chrome Web Store listing for a JSON Viewer & Formatter extension published by the user submitting to Hacker News. JSON (JavaScript Object Notation) is the standard data format used by most web APIs — any time a website or app fetches data from a server, the response is often raw JSON, which browsers display as unformatted, hard-to-read text. Extensions like this one automatically detect JSON in the browser tab and reformat it with syntax highlighting, collapsible tree views, and search, making it far easier for developers to inspect API responses during debugging or development. This is a very common category of browser extension, so the "Show HN" post is likely sharing a new implementation or alternative to existing tools like JSON Viewer or JSON Formatter.
