Do Macros still perform a function even if that function is already set in an Excel file?

Sorry for the confusing thread title. Here is an example.

Let's say I program a macro to turn filters on in the header row. But then I run that macro in a file that already has filter on in the header row. In that case, will the macro then turn off the filter?

Another example:

Let's say I program the macro to unwrap the text, then I run the macro in a file where the text is already unwrapped. Will it then end up wrapping the text instead?

That depends on the command used in the macro. Most of the time, the commands perform a specific function, this command is to only turn on something or this command is only used to turn off. Depending on the command sometimes its okay to be redundant and will not break the code, but sometimes there is a preset limit and if you try to do something that is already on it will give you an error.

So in these examples, I am performing the command from the ribbon at the top. For filter, I go to the Data tab and click the Filter button. For unwrapping text, I am going to the Home tab and clicking the Wrap Text button.

off the top of my head i know that filter that on and off are separate.

The command is not the same as the button you press. The easiest thing to do is to press record macro and click a button that toggles between something. Then stop the macro record and look at the code, you see if the command the macro picked up repeats in that case it does toggle and you can use the same command but if you see two different commands then you would know that the button actually does 2 different things.
