Try a spreadsheet formula right on the page
A live sheet inside the lesson: paste the formula your AI chat gave you and watch what it does to real cells.
Some lessons now carry a small working spreadsheet. Type or paste a formula, and the sheet calculates it on the spot, with the same functions you use in Excel: lookups, conditional sums, counts by criteria and ranges.
It is built for the moment an AI chat hands you a formula you don't fully trust. Run it on the lesson's data first, see which cells change, and ask your Maestro about anything that looks off.
