ISNUMBER Function

The ISNUMBER function in Excel checks whether a value is a number. It is useful for determining if a cell contains a numeric value.

Syntax:

ISNUMBER(value)

• value: The value you want to test to see if it is a number.

Examples:

1. =ISNUMBER(123) would return TRUE.
2. =ISNUMBER("Excel") would return FALSE.
3. =ISNUMBER(A1) would return TRUE if the cell A1 contains a number, otherwise FALSE.
4. =ISNUMBER("123") would return FALSE.

Note: The ISNUMBER function is especially helpful when analyzing data sets to ensure that numeric operations are only performed on numeric data.
