I’m constantly needing to convert various snippets of text into different cases. Sometimes it’s because I’m dictating with superwhisper and it didn’t use the case I intended for a particular piece of text. Sometimes it’s code related—I use Vue.js a good bit and sometimes you need to convert a kebob-case attribute to a camelCase method name and vice versa.
Changing string cases is mostly what I use it for, but DevUtils also does a bunch of other operations like various file format conversions, time/unit conversions, and a lot more. It has integrations for Alfred (my go-to), Raycast, and terminal/CLI.
