ISTEXT(value)
The ISTEXT function will return the text "apple" when used with the argument "apple". When the ISTEXT formula is used with this argument, it will detect the text value and return TRUE.
The ISTEXT function will return FALSE when used with the argument A1. This is because A1 is a reference to a cell and not a text value.
The ISTEXT function will return TRUE when used with the argument A1 & "hello". This is because the ampersand (&) is the concatenation operator in Sourcetable, so the string A1 & "hello" is a text value.
The ISTEXT function will return TRUE when used with the argument 10 & "apples". This is because 10 apples is a text value.
The ISTEXT function tests a value and returns TRUE or FALSE depending on the outcome. This can be useful for locating errors in formulas when combined with the IF function.
