Now once it is in Access, I want to convert those values back to numbers and only those values.
If you are talking about changing only some of the values in the table from text to numeric, then you can't. Access is not Excel, and doesn't have that functionality. when you define a table in Access, any one field can contain only one type of data (text, numeric, etc.); you cannot mix them. A 'text' type field can contain data (strings) that look like they are numeric, bu in fact they are not. But it doesn't work they other way around - a numeric type field cannot contain non-numeric data.

You could use a Select query to display numeric data in numeric form (i.e. right justified) rather than as text, but I don't see what the advantage would be.
