CSS to SASS/SCSS converter

Some years ago, I shifted from self-written CSS files to preprocessors, first LESS and then SASS (but with the SCSS syntax) for all new projects that are gonna be larger than about one day of development. If I already happen to have "normal" CSS code (e.g. from a template or another project), I use this website to convert it. Just paste the CSS on the left side, hover over to the button in the middle and select between SASS and SCSS syntax (whichever you prefer, I recommend SCSS) and you get your converted code on the right side.

DeepL Translator

Google Translate is great, sure, but DeepL is a just the right bit better to be worth mentioning. It translates sentences with correct grammar and is in general quite a bit better. The only downside currently is the lack of supported languages.

keycode.info

Let’s be honest, JavaScript KeyCodes are not that great. Finding out the right KeyCode can be a very annoying task. Here’s where keycode.info steps in. This simple website will show you the KeyCode for the button you just pressed on your keyboard. This saved me a lot of time and annoyance in the past.

Postman is a tool that allows you to test your APIs easily. Type in the URL, set parameters to pass and the mode (e.g. GET or POST) and call it. The only downside is that you

Online Regex testing and debugging tool. Since I’m not a regex expert, I wrote almost all of my regexes with this tool. It also supports some language specific Regex engines like PCRE (PHP), JavaScript, Python and Go. It also features a share option, so you can share your regex example on sites like Stack Overflow.

Replace Cover

Replace Cover is a great tool to give your own Spotify playlists a bit of the look and feel of the playlist covers made by the company. It’s very simple to use and is a bit limited in features currently, but I’m hoping for future updates to extend this. From my understanding, the images come from pngimg and Unsplash, so there should not be any copyright issues. Replace Cover

Total Commander FTP password decryption

I use Total Commander to access my FTP servers and because I couldn’t change the password and I haven’t it saved elsewhere, I forgot it at some point or needed it for some other reason. But those passwords are encrypted, and stored in the file %appdata%\AppData\Roaming\GHISLER\wcx_ftp.ini. Copy that encrypted string to the tool’s input box and hit the decryption button. Now you should see your password in plain text.
