Quantify 'Show Changes' Data

[Randall]

I currently run a quote team with assigned lines to various members. I've run into an issue with some users not working their lines and others covering for them. I'm noticing a trend of the same users over and over not pulling their weight. I am able to see who changed the cells assigned to each member, but I'm wondering if there is a way to quantify that data quickly via excel.

For example, the 'Changes' tab shows each cell and who it was changed by. I'm wondering if their is a way to pull that data in and show how many cells each user changed.
