Most people think Excel’s function count is a measure of power. They’re wrong. Counting functions is like counting words in a dictionary and assuming fluency follows. You can list 498 Excel functions — but if you’ve never used LET(), FILTER(), or XMATCH() in production, you’re operating at 12% of Excel’s current capability.
The Problem
Teams waste hours writing redundant formulas because they don’t know which functions exist — or worse, they assume older ones (like INDEX+MATCH) are still the best choice when newer alternatives do more with less. Here’s a real snapshot from a finance team’s Q1 sales tracker (A1:F11) before cleanup:
| Sales Rep | Region | Q1 Revenue | Status | Formula Used (Cell E2:E11) | Notes |
|---|---|---|---|---|---|
| Sarah Chen | APAC | $45,200 | Target Met | =IF(B2="EMEA",IF(C2>=50000,"Target Met","Below Target"),IF(B2="APAC",IF(C2>=40000,"Target Met","Below Target"),"N/A")) |
Nested IF (7 levels deep) |
| James Okafor | EMEA | $62,100 | Target Met | =INDEX($G$2:$G$5,MATCH(1,(B2=$F$2:$F$5)*(C2>=$H$2:$H$5),0)) |
Array formula — Ctrl+Shift+Enter required |
| Lena Petrova | Americas | $31,800 | Below Target | =VLOOKUP(B2,$F$2:$I$5,4,FALSE) |
Breaks if column order changes |
| Rajiv Mehta | APAC | $49,600 | Target Met | =IF(ISERROR(VLOOKUP(B2&"|"&C2,$J$2:$K$20,2,FALSE)),"N/A",VLOOKUP(B2&"|"&C2,$J$2:$K$20,2,FALSE)) |
Concatenation hack for 2D lookup |
| Maya Torres | EMEA | $57,400 | Target Met | =SUMPRODUCT((B2=$F$2:$F$5)*(C2>=$H$2:$H$5)*$I$2:$I$5) |
Hard to audit; no error handling |
| Diego Silva | Americas | $28,900 | Below Target | =CHOOSE(MATCH(B2,{"Americas","APAC","EMEA"},0),IF(C2>=35000,"Target Met","Below Target"),IF(C2>=40000,"Target Met","Below Target"),IF(C2>=50000,"Target Met","Below Target")) |
Hardcoded region list; fragile |
| Aisha Khan | APAC | $39,100 | Below Target | =IF(AND(B2="APAC",C2>=40000),"Target Met",IF(AND(B2="EMEA",C2>=50000),"Target Met",IF(AND(B2="Americas",C2>=35000),"Target Met","Below Target"))) |
Repeats logic; unreadable |
| Tariq Al-Farsi | EMEA | $48,300 | Below Target | =XLOOKUP(B2&"|"&C2,$J$2:$J$20,$K$2:$K$20,"N/A") |
Better, but still concatenating |
| Priya Nair | Americas | $36,700 | Target Met | =IFS(B2="Americas",IF(C2>=35000,"Target Met","Below Target"),B2="APAC",IF(C2>=40000,"Target Met","Below Target"),B2="EMEA",IF(C2>=50000,"Target Met","Below Target"),TRUE,"N/A") |
Slightly better — but still repetitive |
| Kenji Tanaka | APAC | $51,200 | Target Met | =SWITCH(TRUE,AND(B2="Americas",C2>=35000),"Target Met",AND(B2="APAC",C2>=40000),"Target Met",AND(B2="EMEA",C2>=50000),"Target Met","Below Target") |
Cleaner — but still manual thresholds |
The Solution
We replaced all ten formulas in column E with one elegant, dynamic, self-documenting formula in E2 — then copied down. The key wasn’t learning *more* functions. It was using the right *combination* — and knowing where to store logic.
- Move thresholds into a table: Paste region targets into F1:H4 as a clean, named range
RegionTargets. Use headersRegion,MinRevenue,Status. - In E2, enter this single formula:
=XLOOKUP(B2,RegionTargets[Region],RegionTargets[Status],"N/A",0,1)— but wait, that only checks region, not revenue. So instead, use=LET(region,B2,revenue,C2,threshold,XLOOKUP(region,RegionTargets[Region],RegionTargets[MinRevenue]),IF(revenue>=threshold,"Target Met","Below Target")) - Press Ctrl+Enter to fill E2:E11 — no dragging needed. Excel auto-expands the dynamic array.
The beauty of this approach is that updating a target now means editing one cell in RegionTargets — not rewriting ten formulas. And LET() makes the logic readable, debuggable, and reusable.
| Sales Rep | Region | Q1 Revenue | Status | Formula in E2 (copied down) |
|---|---|---|---|---|
| Sarah Chen | APAC | $45,200 | Target Met | =LET(r,B2,rev,C2,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| James Okafor | EMEA | $62,100 | Target Met | =LET(r,B3,rev,C3,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Lena Petrova | Americas | $31,800 | Below Target | =LET(r,B4,rev,C4,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Rajiv Mehta | APAC | $49,600 | Target Met | =LET(r,B5,rev,C5,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Maya Torres | EMEA | $57,400 | Target Met | =LET(r,B6,rev,C6,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Diego Silva | Americas | $28,900 | Below Target | =LET(r,B7,rev,C7,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Aisha Khan | APAC | $39,100 | Below Target | =LET(r,B8,rev,C8,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Tariq Al-Farsi | EMEA | $48,300 | Below Target | =LET(r,B9,rev,C9,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Priya Nair | Americas | $36,700 | Target Met | =LET(r,B10,rev,C10,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
| Kenji Tanaka | APAC | $51,200 | Target Met | =LET(r,B11,rev,C11,t,XLOOKUP(r,RegionTargets[Region],RegionTargets[MinRevenue]),IF(rev>=t,"Target Met","Below Target")) |
Going Further
You can extend this in seconds. Add a new column F2:F11 with =FILTER(A2:A11,E2:E11="Target Met") to auto-list top performers — no manual filtering. Or wrap the LET() in an IFERROR() to handle missing regions cleanly. What makes this elegant is how LET() lets you name variables inside formulas — something Excel lacked for 35 years until 2020. And yes, it works in Excel for Microsoft 365 and Excel 2021 (but not Excel 2019 or earlier).
Surprising tip: TEXTJOIN() with FILTER() beats CONCATENATE() every time — try =TEXTJOIN(", ",TRUE,FILTER(A2:A11,(E2:E11="Target Met")*(C2:C11>50000))) to get names of high-performing APAC/EMEA reps over $50K — in one cell.
When NOT to Use This
- If your workbook must be compatible with Excel 2016 or earlier — skip LET(), XLOOKUP(), and FILTER(). Stick with INDEX+MATCH + named ranges.
- If your data source is volatile (e.g., live Power Query output that refreshes mid-calculation), avoid nested LET() with multiple XLOOKUPs — use helper columns instead.
- Never embed complex logic directly in reports meant for non-technical stakeholders. Move the
RegionTargetstable to a hidden 'Settings' sheet — keep formulas simple and transparent.
