Importing pdf form into Excel 2007 gives me a blank form

Question

Howdy.  I am using Excel 2007 and I choose Insert - Object - Adobe Acrobat Document. When the pdf is inserted I see the form but every field is now blank. I am using Adobe Reader X to review the forms I receive. I do not know when version the original form was created in. Even if I save the form in Reader X and then import it, it is still blank.  Does anyone know how to keep the data in the form?
Thanks

Answer 1

Form fields and annotations (such as those available on the Review & Comment toolbar) are not part of the core PDF page content. 
Form fields and annotations are objects that are associated with a location on a PDF page.
Core content of a PDF (including the glyphs that depict textual content) are graphic objects "painted" to the PDF page by the PDF creation process.
A simple way to see this is to create two simple 1 page PDFs having different page content.
On the first PDF, add a form field and an annotation. Save. Now, use  Replace Pages to replace PDF#1 with PDF#2.
Or, do the opposite.  Either demonstrates that form fields and annotations are not part of the core PDF page content.
Simplistic, but convenient is to consider form fields/annotations as on a separate "layer".
The "meat and potatoes" are in ISO 32000-1.
Adobe's ISO approved copy of ISO 32000-1 (The PDF ISO Standard):

What is inserted into the Excel file is the core PDF page content.
Using Acrobat Pro:
To "flatten" form fields into the PDF page content you could use Acrobat's Optimizer or a Preflight.
To "flatten" annotations into the PDF page content you could use an Acrobat Preflight.
