Logical Functions Foundations
Learn how Excel logical functions test conditions, combine rules, and return clear decisions in practical worksheet workflows.
And Function
Returns TRUE only when every logical test is TRUE.
False Function
Returns the logical value FALSE, which Excel also treats as 0 in many calculations.
If Function
Test a condition and return one result if it is TRUE and another if it is FALSE.
Iferror Function
Return a fallback value when a formula produces an error such as #DIV/0!, #N/A, or #VALUE!.
Ifna Function
Return a fallback value only when a formula returns #N/A, which is especially useful for lookups.
Ifs Function
Test multiple conditions and return the result for the first one that is TRUE.
Not Function
Reverses a logical result so TRUE becomes FALSE and FALSE becomes TRUE.
Or Function
Returns TRUE when at least one logical test is TRUE.
Switch Function
Compare one expression against a list of values and return the matching result.
True Function
Returns the logical value TRUE, which Excel also treats as 1 in many calculations.
Xor Function
Returns TRUE when an odd number of logical tests are TRUE.
"Mastering logical functions is about building resilient decision-making engines in Excel. This path focuses on nesting IF, AND, and OR logic to automate complex business rules and data validation workflows."
"By the end of this module, you will be able to construct multi-layered logical tests that handle edge cases and ensure data integrity across your most critical business models."
