Is JSON Formatter Pro Safe? — Extension Safety Profile

This extension requests access to , which means it can read and modify data on every website you visit. For a JSON formatter, this broad permission allows it to detect and format JSON responses from any server, including those that may contain private information like API keys or session tokens. While this level of access is common for developer tools that need to operate across all sites, it is a powerful permission that users should grant only to extensions they trust.

General browser extensions from individual or lesser-known publishers can carry inherent risks. A common concern is that an extension with such broad permissions could potentially be updated to behave differently, or its publisher identity might be less established, making it harder to verify trustworthiness. Users should be aware that any extension that can see all web page content also sees sensitive data if you are logged into banking, email, or health portals.

Our analysis shows this extension scores perfectly in Maintenance & Ownership, indicating a recent and active update, which is a positive sign. However, its weakest area is Publisher & Identity, with a score of 60%, reflecting limited publicly verifiable information about the developer, who is linked to a generic Google Sites page. This makes it more difficult to assess the long-term accountability and intentions behind the extension.
