Прекрасное расширение для разработчиков! JSON Formatter делает работу с JSON легкой и приятной благодаря множеству тем и удобным горячим клавишам. Рекомендую всем!
This extension has great features and very easy to switch json format types.
Diğerlerine göre bunu daha çok sevdim daha basit
Covers half of screen with non-closeable banner "Your JSON formatter got updated"
This one has sorting option, up up.
Takes my CPU usage to 100% somehow, on brave, latest version
How can I save the config forever ? such as theme...
Does not work on local json files directly. windows11/chrome Version 116.0.5845.141
This is an excellent and performant extension! Definitely the best JSON formatter extension I've found!
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!
