Interesting article and at the bottom he mentions "You can try out Row Zero without signing up (I love when apps let you do that)." You know what, I love that too! Let me try it. Lets see how it does with the AWS EC2 Pricing List for us-east-1. 229Mb and 320k rows. To say it was shocking how fast it loaded might be an understatement. Google Sheets (although it looks like it has _much_ more functionality as far as spreadsheets go) absolutely chugs trying to load a third of this data.
