One additional item to consider is whether or not the user is familiar with PPT. We have found that the skill level among screen reader users with both PPT and Excel really varies and is generally dependent upon whether they regularly use the program as a part of their job. Thus people who use screen readers and give a lot of presentations are highly skilled and can get to embedded content like spreadsheets, but the average user has not been able to do this. We recommend keeping things simple for PPTs that are distributed to a general audience.

Keep in mind that it depends on which view of the presentation you are
providing to participants. If you are giving them the presentation or PPTX
document then Excel and Word content that has been embedded will be
accessible and you can open the original Excel or Word document from the
slide/provided it is in the same folder as the PowerPoint document and is
available to participants. However if you provide the PowerPoint show, the
OLE objects such as the Excel or Word documents or pieces of content from
them will not be accessible and will be objects that require Alt Text. It is
the same if you convert the PowerPoint document to tagged PDF...those linked
objects that were accessible in the Normal slide view of the presentation
are figures that require Alt Text.

I did a workshop yesterday on accessible Office documents and the key for
PowerPoint is to decide how the PowerPoint document will be distributed
before you begin adding content because that determines what type of content
you can add to slides.

Cheers, Karen

Really? That is pretty neat that Excel data is accessible in PP, I did not
know that.
If you don't mind, I'd love to get a copy of an accessible pp set with Excel
data, just to see how it works.
Onlyif it is convenient.
Thanks
