Basic JSON Formatter

Name: Basic JSON Formatter
Rating: 4.6154 (13 reviews)
Author: Dr. McKay

Adds a page action to pretty-print JSON. Unlike similar extensions, this simply pretty-prints it. It doesn't add any kind of viewer, colors, or collapsing. If you want this to work as expected, disable devtools.jsonview.enabled in about:config.

Features & Capabilities

Basic JSON Formatter is a lightweight Chrome extension that adds a simple button to the address bar, allowing users to pretty-print JSON content with ease. Unlike other JSON viewers, this extension focuses solely on formatting JSON data without adding colors, collapsible sections, or advanced viewing options. This minimal approach ensures a clutter-free experience for users who need to quickly and clearly view JSON responses.

The extension activates only when the current page's content type is application/json or contains valid JSON. For optimal functionality, users should disable devtools.jsonview.enabled in about:config to prevent conflicts with Chrome's native JSON viewer. Basic JSON Formatter is perfect for developers and users who prefer a straightforward and clean JSON display without distractions.

Is Basic JSON Formatter Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Basic JSON Formatter requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
