Google sheets is a no brainer, you can share easily, collaborate and even access from different devices anywhere with Internet access. 
I've done our club results with Google sheets for a few years now and use it for allsorts of slot car related stuff.  I use it for handicaps, club signon sheets, race calendars, I made one to find out the ground clearance when using different diameter tyres and different offset slotit pods, I even use it for all my 3D printed data including full size car dimensions to 1/32 and 1/24 scale.
