This may be a bit clunky, but I'll suggest it anyway just in case it helps.

Assuming all the invoices are 1 page, you could select them all, and export them to PDF, then use something like PDF24 to split the resulting PDF into individual files.

You would need to then rename and save each file in the right folder.

Not sure if this will work for you or not?

An interesting idea. I'm quite used to splitting pdf's by using Print to pdf for just page 4, page 5 etc, but hadn't heard of PDF24 - it looks like that could be a smart move. Thank you.

No problem.

The main thing we use it for is password protecting PDFs but it is quite a versatile tool.
