Use this app instead of Excel to directly edit CSV files – Lifehacker

ModernCSV, an indie app for Linux, Mac, and Windows computers, is the best tool I’ve come across for this purpose. If you work with CSV files frequently, or just need to edit one quickly, it’s worth checking out. This application is built specifically with CSV files in mind and makes working with them simple. … There’s even a command bar, triggered with the keyboard shortcut CLTR/CMD-L. This lets you quickly use any of the commands offered by the application without needing to learn the dedicated keyboard shortcut—just type what you want to do and hit enter.
