In-depth safety analysis
This extension requests the "" permission, which allows it to read and modify data on any website you visit. For a JSON formatting tool, such broad host access is typical—it needs to detect JSON responses on arbitrary pages to format them—but it means the extension can technically view all browsing content, including sensitive information, if misused.
General browser extensions that interact with page content are frequent targets for phishing clones or supply-chain compromises. A careful user should examine the publisher'ss identity and reviews closely. The fact that this publisher uses a generic Google Sites page provides less publicly verified identity than a dedicated developer domain, so it's wise to double-check that you're installing the authentic extension and not an imitation.
In the supplied safety assessment, the weakest dimension is Publisher & Identity (60/100), indicating limited independent documentation of the developer'ss background. The strongest dimension is Maintenance & Ownership (100/100), reflecting active updates and maintenance—a positive signal for vulnerability patching. Together, these scores place the extension in a moderate trust tier.
