1. Paste 20 bank narration lines (remove account numbers) and ask: 'Categorise each into Salary, Rent, Utilities, Vendor payment, Customer receipt, Bank charges or Other. Return a 2-column table.'
2. Paste 15 messy company names and ask for a standardised version (e.g. 'M/s Sharma Trdrs' -> 'Sharma Traders').
3. Ask: 'Instead of cleaning these rows, give me Power Query steps / an Excel formula that does it for any number of rows.'
