Jeremiah Ihab Samuel (ID: 00000090d7944527) Voted 5 ★ - Updated 05/12/2023 I highly recommend the JSON formatter tool. In my experience, it is the best one I have ever used. It has become an essential tool in my API work, and I feel like something is missing when it's not installed. Thank you so much!

Max Shapira (ID: 000000b507cb7c91) Voted 5 ★ - Updated 03/18/2023 Thank you for this awesome extension! Great job. But one thing that is quite annoying and distracting is seeing the toolbar every time you load the page. The toolbar should be hidden when the page loads and only display if the user chooses to toggle it on.
