How to sync my Excel workbooks on pc/tablet, using OneDrive

Hello,
I recently found out that it should be possible to 'copy' a pc-Excel-workbook to my Samsung Android tablet and sync it there. This would be useful for the (big) trip schedule and expense tracker that I created on pc.
Would be nice if I could keep it updated from my tablet during the actual trip - I will not carry a laptop around...
I found out that I can create a Microsoft account (I did so) and use OneDrive to keep both files synced. But there I get lost.

I succeeded in connecting both devices and keep the TRIP SCHEDULE synced, but... only if I keep working with it online. But I wished I could keep working on the schedule in my (offline) EXCEL application and from there automatically 'export' all changes to my tablet - and vice versa.

Is that possible? And how?
Please don't expect to much from me in terms of understanding syncing issues. So be 'careful' and 'patient' in your assistance. Thanks in advance!

I use Windows 7, 64 bit and Microsoft Office Professional Plus 2010, 64 bit.

Greetings,
Wim
