Importing supplier invoices

I have had to change PCs and have tried to import supplier invoices from the previous one. I have managed to use the export wizard to send it to an excel file but there does not seem to be a similar import wizard to get them onto the new PC. How can I get this done?

backup > restore works fine in dolibarr… but that’s based on my self-hosted version. If you’re using doliwamp etc then I’m not sure.
