How to export/import VBA code from one workbook to another?

I've been working on some VBA code in a sample spreadsheet. I have 4 command buttons on a new sheet, 4 user forms, and 4 modules. Rather than than manually copy/paste between 2 workbooks, how can I easily export the code from one workbook to another?

Manually copying and pasting now would not be that big of a deal. However, if I ever have to modify the code, I will have likely forgotten a lot of how VBA works, so I need a mostly automated process.

I found Chip Pearson's article about doing that sort of thing, but it's more like a textbook than a usable process or procedure.

Is there a built in function, or some easy way to do this? Ideally, I would like for this process to be accomplishable by a nonprogrammer techie person.

So, what you're telling me is that there is no way to export them all at once. Seems strange that even if there isn't a built in function, there's not code or an addon to do the job all at once.

I didn't see Sintek's reply until I came here to update the thread. I will try those and see if they work.

However, I also found something else and wanted to see if anyone had worked with this solution. Chip Pearson published an Import/Export module. I am able to export all the files fine. However, the import part is not working properly. I have used both of his install spreadsheets, ran Excel as an administrator while running both spreadsheets, enabled the "Trust access to the VBA project model", and am still unable to use the multi-import function. I see it in the menu, but clicking on it does nothing. I have called Chip (he has his number posted on his website), as well as sent some emails. I have not heard back in a week. It looks like this module was made a while ago, so I'm not sure it will work with Excel 2016. Has anyone gotten these to work?
