Criteria & aggregation
| Formula | What it does | Example |
| SUMIF | Sum where criteria match | =SUMIF(A:A,"East",B:B) |
| SUMIFS | Sum with multiple criteria | =SUMIFS(C:C,A:A,"East",B:B,">100") |
| COUNTIF | Count where criteria match | =COUNTIF(A:A,">100") |
| COUNTIFS | Count with multiple criteria | =COUNTIFS(A:A,"East",B:B,">0") |
| AVERAGEIF | Average where criteria match | =AVERAGEIF(A:A,"Yes",B:B) |
Lookups
| Formula | What it does | Example |
| XLOOKUP | Modern lookup (any direction) | =XLOOKUP(E2,A:A,C:C,"N/A") |
| VLOOKUP | Lookup in first column (legacy) | =VLOOKUP(E2,A:C,3,FALSE) |
| INDEX/MATCH | Flexible two-way lookup | =INDEX(C:C,MATCH(E2,A:A,0)) |
Logic & text
| Formula | What it does | Example |
| IF | Conditional logic | =IF(B2>=60,"Pass","Fail") |
| IFS | Multiple conditions | =IFS(B2>=90,"A",B2>=80,"B",TRUE,"C") |
| TEXT | Format number as text | =TEXT(A2,"YYYY-MM-DD") |
| CONCAT | Join text | =CONCAT(A2," ",B2) |
| TEXTJOIN | Join with delimiter | =TEXTJOIN(", ",TRUE,A2:A10) |
Dynamic arrays (Microsoft 365 / 2021)
| Formula | What it does | Example |
| FILTER | Dynamic filtered array | =FILTER(A2:C100,B2:B100>50) |
| UNIQUE | Distinct values | =UNIQUE(A2:A100) |
