Thanks Alec, and sorry I might not have been clear. I have no problems converting files to Adobe while I’m on my laptop running Microsoft Office. My question was for an Android Tablet, specifically the Samsung Galaxy Tablet. I want to be able to take a spreadsheet on the tablet, which I’m working it with Polaris (or other similar app) and save a copy in PDF format so that I can then open it with Adobe Reader for Android tablets, and add a signature to that file. Do you think it is doable?
