Do you not have the manual?

Correct, That means that its time for the Inspection service to be done on
your car. Without the manual and proper documentation it may be hard to see
if you need Inspection 1 or 2 done. With that many miles im going to guess
that its time for Inspection 2 service to be done. Some cases BMW can pull
up service records via VIN and see what has been done, but that would be up
to the previous repairs shops to document it in the BMW system.

As far as the Excel issue. It could be something they will find during the
inspection, or it might be something you need to mention so they can look at
that more closely.

Services typically go like this:

15,000 = Oil Service (Average price for mine is $120-150USD*)
30,000 = Inspection 1 (Average price for mine is $3500-400USD*)
45,000 = Oil Service
60,000 = Inspection 2 (Average price for mine is $800-950USD*)
75,000 = Oil Service
90,000 = Inspection 1

and repeat, Now your COULD have been done sooner or out of that order, not
knowing your car or the manual it would be hard for me to say. I would
consult with your local BMW Authorized Repair Center.
