Three formulas that solve
real Monday-morning problems.
Not theory. Not textbook examples. These are the formulas our students use the day after their first lesson.
INDEX-MATCH
Never get a #N/A again.
Your VLOOKUP breaks every time someone adds a column. Sales data mismatch costs you 40 minutes every Monday.
INDEX-MATCH looks up from any direction, survives column insertions, and runs 30% faster on large datasets.
=INDEX(D:D, MATCH(A2, B:B, 0))SUMIFS
Multi-condition totals in one cell.
Your manager wants Q3 revenue broken down by region and product category. You're using 6 separate SUMIF formulas.
One SUMIFS with multiple criteria ranges. Combine with a dropdown for instant filtered totals — no pivot table needed.
=SUMIFS(Revenue, Quarter, "Q3", Region, "West")Dynamic Arrays
One formula. Entire columns.
Copying formulas down 500 rows, then updating each one when the data changes. Two hours of your Thursday, gone.
FILTER, SORT, and UNIQUE spill results automatically. Change the source data — the output updates everywhere at once.
=FILTER(A:C, B:B="Active", "No results")The cheatsheet includes 24 more formulas with real-world examples.

Dynamic arrays filter by stage. SUMPRODUCT weights probability. Forecast updates as deals move.
Campaign reports in slides
Building weekly campaign reports in PowerPoint. Each slide manually updated. Meetings spent explaining the data.
The dashboard that got her promoted
LAMBDA functions + dynamic charts. One source of truth. The CMO stopped the meeting and said "who built this?"
Financial model in 40 tabs
A 40-tab model built over 3 years. Nobody else could use it. Circular references nobody dared to fix.
Clean model, one tab of logic
LET and LAMBDA collapsed 40 tabs into 8. Self-documenting formulas. Board can now audit it themselves.

These are the messages we get. Specific, because the results were specific.
"I built a dashboard in my second week that my manager had been asking for for six months. She forwarded it to the VP. I'm not the same person at work."
"I used to apologize before sharing my screen. Now people ask me to slow down so they can take notes. INDEX-MATCH alone changed how my team sees me."
"The case study format made it click. I wasn't learning formulas — I was watching someone solve the exact same problem I had on my desk that morning."
