Hi Andy,
To handle data imports from this file type will require a custom plugin. If you’re interested, send me an email at jonah@floop.app and we can discuss making something for you. Depending on what you want, I expected this should take me a few hours (70 US / hour) so roughly 200 - 300 $
If you have experience with code and want to learn how to make a plugin, I offer coaching for that as well.
Have a good day and good luck!
