Returns TRUE if any of the arguments are considered TRUE, and FALSE otherwise.
OR(argument1; argument2 ...argument30)
argument1 to argument30 are up to 30 arguments, each of which may be a logical result or value, or a reference to a cell or range.
OR tests every value (as an argument, or in a each referenced cell), and returns TRUE if any of them are TRUE. Any non-zero number is considered to be TRUE. Any text cells in ranges are ignored.
- returns TRUE.
- returns TRUE, because 5 is considered TRUE.
If cells A5:B8 all contain FALSE, and cell C2 contains =TRUE():
OR(1>2; A5:B8; C2)
- returns TRUE, because cell C2 is TRUE.
- Entering =OR(TRUE; FALSE) in a cell correctly returns TRUE, but the display in the formula bar is =OR(1; 0). See Issue 84266.
