JSONer is a free Chrome add-on developed by Al Cheung. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. JSONer aims to make JSON more readable in Chrome without any configuration required.

With JSONer, you can easily view and navigate JSON files in a more user-friendly format. Instead of being prompted to download or rendering JSON as plain text, JSONer automatically pretty-prints JSON, making it easier to read and understand. The add-on also provides collapsible array and object sections, allowing for effortless navigation within complex JSON structures.

JSONer is a valuable tool for developers, data analysts, and anyone who frequently works with JSON files in Chrome. It enhances the browsing experience by improving the readability and accessibility of JSON data.
