User reviews

From one developer to another, thank you for this. Fantastic work!

Exactly what I was looking for and I'm leaving a review because the developer responds to reviews and updates the extension accordingly (bug fixes, adding features, etc.)

be careful with this extension. It edits your string values removing double spaces. The values you see in the parsed view are not the same values you see in the raw formatted view. I'm removing this extension and look for something else

Extension safety

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.

JSON Formatter requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on.

JSON Formatter is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
