When using expressions, some values depend on other values conditionally. Here are some examples of conditional statements:
- If you oversleep, then you're late to work.
- If you drink a lot of water, then you're hydrated, but if you don't, you're dehydrated.
In expressions, you can approach these conditional situations in a few ways:
IF(condition, then-expression, else-expression)to choose one of the results based on whether the condition evaluates to
IFS(condition1, then-expression1, condition2, then-expression2, ...)to provide a sequence of condition-value pairs that are evaluated left-to-right until one of the conditions is true.
SWITCH(expression, value1, result1, value2, result2, ..., default_result)to choose one of the results based on the value of the expression.
Expressions may be used in various AppSheet features--app formulas, initial values, virtual columns and column constraints (
Valid_If)--to customize app behavior and provide your users with advanced functionality.
