The ask

Sent verbatim as the prompt. The agent works in a copy of the workspace below and sees nothing else.

How many coffee subscribers did we have each month this year, January to June, and how many cancelled? Work it out from the billing export and the help desk tickets and save it as subscriptions.xlsx with the counts as formulas. My note explains how I count.
