Hi @lesjames
Unfortunately, I am unaware of an export tool for the options page.
I would search through google for a plugin that exports data from the wp_options table.
Worst case, you could grab the code from the ACF core/actions/export.php file, then just write your own loop of options page data, then create your own file.
Not sure how you would import it though…
Sorry I can’t be of much other help.
