Few differences I'd call out:
- If you have summary tables with formulas we'll auto-extend those tables as we see new periods in your data. e.g. If you have "revenue by month" calculated using SUMIFs on top of charge data and we see a new month, we'll copy your formulas down/across.
- Any charts based off those tables will also update. Sheets doesn't do either of these things.
- Finally, people who've switched from Sheets have found our query UX to have much tighter iteration loops by being more deeply integrated into the product.
