# IF Function

Evaluates a logical expression and returns one value when true or another when false.
Sample usage
IF([Due Date]1 > [Due Date]2, "Date 1 is Larger", "Date 2 is Larger")

## Syntax

`IF(logical_expression, value_if_true, [value_if_false])`
• `logical_expression`
The expression to evaluate. Must be true or false.
• `value_if_true`
The value or formula to return if the logical expression is true.
• `value_if_false`—[optional]
The value or formula to return if the logical expression is false. If omitted, a blank value is returned.
Usage notes
• You can nest IF functions to perform multiple logical evaluations.
• Smartsheet reads the IF statements in the formula from left to right, displaying a value based on the first expression to evaluate to true. When nesting IF functions, the optional return_if_false will be returned only if all logical expressions evaluate to false.
Examples

This example references the following sheet information:

Row #Item NumberStatusOrder DateIn Stock?
1C001Green12/15/19true
2C002Red12/12/19false
3C003Yellow12/15/19true
4C004Green12/20/19true

Given the table above, here are some examples of using an IF() function in a sheet:

=IF([Status]1 = "Red", "At Risk", "On Time")IF the "Status" column row 1 equals “Red”, return the value "At Risk”, if not return the value “On Time”.On Time
=IF([Order Date]2 < TODAY(), "Red", IF([Order Date]2 > TODAY(), "Yellow", IF([Order Date]2 = TODAY(), "Green")))

IF the “Order Date” column row 2 is less than TODAY, return a “Red” value.

IF the “Order Date” column row 2 is greater than TODAY return a “Yellow” value.

IF the “Order Date” column row 2 equals TODAY return a “Green” value.

Red
=IF([Order Date]3 < TODAY(), "Red", IF(AND([Order Date]3 >= TODAY(), [Order Date]3 < TODAY(+7)), "Yellow", "Green"))

IF the “Order Date” column row 3 is less than TODAY return a “Red” value.

IF the “Order Date” column row 2 is greater than or equal to TODAY, AND less than the next 7 days, return a “Yellow” value.

If neither applies return the value “Green”.

Yellow
=IF(COUNTIF([Item Number]:[Item Number], [Item Number]@row) > 1, 1, 0)

Search for duplicates:

IF the "Item Number" column has more than one instance of the current row's Item Number, then check a checkbox on this row.

Otherwise, if there are no duplicates, do not check the checkbox.

No rows checked
