The function returns a TRUE logical value, if the value argument is a non-text value. such as a number, date, error message string, or logical value.

Tips

  • You can use the ISNONTEXT function as a logical test inside an IF function.
    =IF(ISNONTEXT(A1),”Non-text”,”Text”)
  • The function returns TRUE for empty cells. On the other hand, if a formula returns an empty string (“”), the cell will look empty in the Excel interface, but the ISNONTEXT function will return FALSE in this case, as Excel considers the space character to be a non-empty value.
  • IFERROR function can return a specific value if case of an error, and can be useful for error handling.
