Sublime is great for hacking your way through a CSV file very quickly. I write in Sublime at least 20% of my formulas and then paste it into Tableau and Talend. Easier (even without autocompletion) than working in a small window/pane than I usually have inside that tools, plus I use a new line for every change, so I can see what I had before (there is no version control for Business Intelligence).
