| Notes / Comments / Advice / Warnings |
| Note: |
As this is a function for determining value type, it does not return errors when an error value is passed, as that is not a reference, so in that case, it returns FALSE. |
| Note: |
For a list of the error values in Excel and their causes, see the Ready Reference article: Excel Error Values. |
| Comment: |
This function is not as widely used as was once the case, as the introduction of the IFNA function in Excel 2013 simplified the identification and handling of errors. |
