Webi export to Excel - numerics as text

I am trying to verify that what I see is happening is in fact the expected behavior.

In Webi am saving a document as Excel 2007.  The saved Excel file has many fields which appear should be numeric but are in fact identified as TEXT in Excel.

What I see is the following:

1. If the BO formula for the field contains a hyperlink it will consider it TEXT in BO – even if the value being shown is a regular NUMERIC value.  I know it is being recognized as TEXT in BO because if I try to format the field – the “Number” tab does not show up.  The exported Excel also sees it as TEXT.
2. If the BO formula uses the FormatNumber() function to display the values -  the cell will be treated as TEXT in BO and Excel will see it as TEXT.

For “2” I can get rid of the FormatNumber function and format the field using the regular Format option – then the BO field is NUMERIC and the field shows up in Excel as numeric.

For “1” I do not see a way to get the field to be a numeric – especially when exported into Excel.  Is there a way to do this?

Thanks
