Assalaamu alaykum wa rahmatullaahi wa barakaatuhu. My father asked me for a spreadsheet to calculate some math necessary for shipping the stuff in our house because we will be migrating to another country, Allaah willing. Among the things that he will ship (and hence use my spreadsheet for) are the TV's. I know that they will commit at least some sins through watching TV; I am 99% sure that they will not mute it when watching the news or that they will let a guest watch whatever they want, and maybe once in a blue moon they might watch a movie. So should I make this spreadsheet? Is it haram to make it? He will also use it for the fridge, oven, washing machine, and whatever else Allaah wills.

All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger. 

Obey your father and prepare the mentioned spreadsheet. You are not sinful in doing that and what you will do does not involve helping in committing a sin.

Allah knows best.
