Answer 1

According to the documentation at 18.18.11 ST_CellType:

str (String) Cell containing a formula string.

So you would only use your first example if a formula was in the <x:v> element.

The second one is used for inline strings and the <x:c> element should have a t attribute of 'inlineStr'. This will just be rich text that will be outputted and not stored in the sharedstring table.

So your first one would be valid like this:

<x:c r="C6" s="1" vm="15" t="str">
   <x:f>CUBEVALUE("xlextdat9 Adventure Works",C$5,$A6)</x:f>
   <x:v>2838512.355</x:v>
</x:c>

Your second one would be valid like this:

<x:c r="B2" t="inlineStr">
   <is><t>btyler</t></is>
</c>
