You're handed a spreadsheet with 5,000 rows of customer data. Some cells are blank, dates are in three different formats, and someone typed "N/A" in the revenue column instead of leaving it empty. A mess.

You paste the first few rows into an AI tool and ask: "Clean this data, standardize the date format, fill in missing values where possible, then tell me the top three insights." Thirty seconds later, you have clean data and a summary: "Your highest-value customers are concentrated in two zip codes, repeat purchases spike every March, and 40% of your revenue comes from just 12% of customers."

That messy spreadsheet just became a strategy document. Today you'll learn to make AI your data analysis partner.
