Trying to ingratiate myself into this project. One of my coworkers is freaking out because she's working in Excel, and just the first part of the project gave her 20k rows. There are more coming. She says she hates Excel, and I'm just looking at her data with my mouth watering. I want in on this project; she's not equipped for it.
To give an example, she had to ask me how to remove all the data in columns A and B without needing to hold Shift and the down arrow for 20k rows. I'm looking at this with possible filters and vlookups, and I know I must have this.
