JSON Formatter: From Open Source to Premium API Tool

I have transitioned JSON Formatter from an open-source project to a closed-source, commercial model to develop a more advanced API-browsing tool with premium features. However, for those who prefer open-source solutions, the final version, JSON Formatter Classic, remains available for use and forking. JSON Formatter is a Chrome extension designed to enhance the viewing and exploration of JSON API responses. It boasts features such as fast performance on long JSON pages, dark mode, syntax highlighting, and collapsible trees with indent guides. The extension is efficient, with minimal impact on non-JSON pages, and supports toggling between raw and parsed JSON. The parsed JSON is accessible as a global variable for inspection in the console.

Installation options include downloading JSON Formatter Classic from the Chrome Web Store or installing it from the source. For development, you can clone the repository and use commands like 'bun run build' for a single build or 'bun run watch' for a watch-driven build. JSON detection relies primarily on the Content-Type header, but also inspects page structure when necessary. The extension accurately reflects JSON parsing limitations inherent in JavaScript, such as the handling of large numbers and object key ordering. For those needing to see the exact server output, the 'Raw' button provides the unaltered JSON data.
