Pull up select one options from external sheet with choice filter

Hey there!

I am new as XLSForm developer. I need to design a form where I have to put cascade select options. I am putting all the data as preloaded, the form hangs up because data is too long.

So I want to put external file (.csv) where I put my data and want to carry in select options on last question answer.

Can anyone help me?
