If you are a web developer, I assume that you handle JSON, HTML, SVG, CSS and sometimes, more rarely JSX, Kotlin, React Native, or even Typescript.
The thing that quickly becomes tricky is to convert all that. For example, converting SVG to JSX or JSON to GraphQL, not forgetting markdown to HTML or HTML to Pug.
In short, if you do this kind of thing, there is an online service (under a free license) simply called Transform.tools which should serve you well.
You write your code in the left box and it is simply converted in the right box. And as you can see, the possibilities of conversions are very numerous.
This is a site to add urgently to your coder toolbox, because it will save you a lot of time!
