The ISNONTEXT Function is to check whether a value is not text. When the value is not text, the result returns TRUE.
Formula:
=ISNONTEXT(value)
Explanations:
Value is required, the result returns TRUE when the value is not text and returns False when it is text.
Example:
=ISNONTEXT(A3)
Cell A3 is a logical value, not TEXT, so ISNONTEXT(A3) returns TRUE.
=ISNONTEXT(A4)
Cell A4 is "6F", a text value, so ISNONTEXT(A4) returns False.
