Improve Excel output and copy/paste of $ and %

Problem/Motivation

Excel output does not follow the similar formatting standards. This includes cells where they should be blank due to merge. Also need to look at the copy and paste of numbers with $, commas, and % signs.

Proposed resolution

Control the excel output per ag-grid standards and format accordingly. Then add some code to remove $, commas, and % from paste on numeric fields. For percentage, also remove but assume it needs to be converted to a decimal.
