» Identifying Numeric Values within a Range Formatted as Text

Problem:

Column A contains both numeric and text values, however, all values are formatted as text.
We want to determine which of the values are actually text (i.e. consist of alphabetic characters) and which are only formatted as text, but are in fact numeric.

Solution:

Use the IF and ISERROR functions as shown in the following formula:
=IF(ISERROR(A2+0),"Text","Number")
