Largeish data wrangling (csv, json)

In response to Ask DN: cheatsheets What are your shortcuts, your hotkeys, your design/dev best practices, the things that make your life easier?

Apps

Sublime Text - with a lot of addons (detailed below)
aText text expander (OSX only). Considerably cheaper ($5) than the original TextExpander (~$30). For instance, each time I need to input a Markdown link I type .mkl and I get []() (otherwise I always forget which bracket is first). Also works great for code snippets.
SCSS
ReCSS bookmarklet - refresh only the css in a webpage, speeds up minor CSS changes
nvALT for quick notes and code snippets
