This isn't some export option, but the data for mine production is publicly available on the wiki: https://www.warzone.com/wiki/Mines
Import this to your spreadsheet app as a basis, and add some dials to adjust mine level, ore production advancements, artifact effects and mine boosting techs and you are done. If you upgrade a mine, you only have to adjust one parameter, if you unlocked a tech, it's just another parameter.
And for army camps you can do something similar. There is no such list for the army camps, but they adhere to a simple formula that you can find in the wiki, too. Add similar dials and you can exactly determine your army income.
I admit, this are only two of the interesting pieces of information, but this should cover most use cases already. For other data you might have to be a little creative ;)
EDIT: This doc from Master Jz should have the same mine data but already formatted: https://docs.google.com/spreadsheets/d/1F5ejYV2bYeaP6yTH683A27iTY8ulDFxGXjwh0zXB82s/edit#gid=1248843523
