With my correction to the second, they're both grammatical and possible. Note that we write the numbers zero to twenty (inclusive) as words, not digits, in most cases.

Very much so, yes. We imagine that the expertise in Excel is a tool with which you can get the job done. For that reason, it goes very nicely with the sense of ability brought by the modal verb 'can'.

It's exactly like saying 'I can screw in a screw with a screwdriver.'
