What's the most repetitive task you still do in Excel every week?

I ran a fun experiment this week.

I took a messy workbook with invoices, customers, transactions, and business data and challenged AI to handle as much of the work as possible.

Instead of asking it to write formulas, I asked it to think like a business assistant.

It built a dashboard.

It highlighted overdue invoices.

It drafted payment reminder emails.

It even created business reports and a presentation based on the same workbook.

It wasn't flawless, but it saved a huge amount of time compared to starting from a blank sheet.

I'm sharing the full walkthrough because I think this is where Excel workflows are heading.

The question isn't whether AI will replace Excel.

The question is how we can use AI to eliminate the repetitive work while keeping full control over the final result.
