Why do I activate Vim in any code editor I work with

Why do I activate Vim in any code editor I work with? 
Imagine a list of emails in a Google Sheet in a single column, one per row, and need to convert it to a Ruby array.

1️⃣ Open Vim
2️⃣ Paste the list
3️⃣ :%s/^/"/ 
4️⃣ :%s/$/",/
5️⃣ Add `[` and `]` 

Done. Enjoy coffee!
