I couldn't catch your point. What Excel sheet do you require for 'Joining Formalities'? This will require a simple 'checklist' of 'Dos' and 'Don'ts' and a checkbox against every item listed therein to confirm whether it has been complied with or not.
You need to maintain a diary or Year Planner to note down target dates for every compliance, which will suffice.
