- (2025-07-24) Dimple Chauhan: This extension does exactly what it's supposed to — formats and colorizes raw JSON responses in the browser, making them much easier to read. It saves a lot of time when debugging APIs or inspecting data structures. I like how it preserves the tree structure and allows me to collapse/expand nodes. The syntax highlighting is clean and easy on the eyes. Also appreciate the ability to copy values or keys easily.
