Not very good to use
Simples e precisa!
Supports multiple custom configurations, I really like it. It would be even better if indentation lines could be added
Very easy and good extensions. I liked the wrap option!
Very easy
Web API 테스트할 때 유용하네요. 아쉬운 점: "YYYYMMddhhmmss" 형식의 시간을 epoch time으로 인식합니다. (ex: "20240625060355" --> "Mon, 27 May 2611 11:51:01 GMT")
Started messing up values whenever I double-click it to select. Seems resolved. Thank you!
Funciona perfectamente, he probado varios y actualmente es el único que funciona.
Very good extension It's indeed very fast even for large files (good for temp large API tests) Maybe you should add a way to add a custom value to the "Auto-format Documents" Another great thing would be a fix for the "Wrap Lines" option cause it doesn't seem to do anything for me (using chromium btw)
Simple and fast
