The major topics that will be covered in this class include:
Introduction to Strategic Formula Use:
- Why choosing the right formula matters: clarity, performance, and maintenance
- Common traps: overusing IF, defaulting to familiar tools, ignoring modern functions
- How Excel offers multiple ways to solve the same problem and how to pick wisely
Conditional Logic and Branching Tools:
- IFS vs SWITCH vs nested IF: comparing readability and structure
- When to simplify logic and how to avoid nested nightmares
Summarizing Data:
- SUMIFS vs SUMPRODUCT: multiple conditions, weighted sums, totals
Filtering and Output Control:
- FILTER vs IF + INDEX: dynamic data extraction with vs without Excel 365
- Trade-offs in backward compatibility and ease of use
Custom Output and Decision Trees:
- CHOOSE vs SWITCH vs LOOKUP: logic trees and category mapping
Embedded Variables and Reusability:
- LET vs named ranges: clarity and efficiency for long formulas
- Using LAMBDA with LET to create custom functions
- Simplifying and documenting complex calculations
Best Practices for Formula Selection:
- Criteria for deciding: readability, flexibility, future maintenance
- Tips for avoiding overengineering and formula bloat
