Initialize multiple variables at the same time, assign each one a form answer, and tidy up all the variables (toupper, trim, replace special characters, etc.)

Hi!

I'm trying to be better at making simple clean flows. So far I have used form answers in a case by case basis, tidying up here and there and using them in e-mails with formatted HTML tables. But now I need to actually start storing a lot of information as SharePoint list items to later use in PowerApps.

Is there a better, cleaner, simpler way to do the following?

Capture the answers from a form.
Initialize multiple variables in one step, one variable for each answer.
Assign an answer to each variable.
Run all variables through a step to make them uppercase, trim leading a trailing spaces, convert special characters (Á, È, Ü) to regular (A, E, U), and so on.

I'm following some tutorials and I have initialized an 'object' type variable and declared the value as:

{

"var1": [form answer dynamic content]

}

But it occurred to me that I don't want to format each line with multiple "replace(replace(replace". Also, I don't want to use the form answers "as is" because in the past I've had problems with random spaces that I could not remove until I've stored the answer as a variable.

Do I need to store all the variables in an array to run them through a "cleaner"? Can I initialize an array variable insted of an object one?

Any help or different approeach is appreciated. Thank you.
