Hi @Nerida KC,
Thank you for posting in this community.
We don't have a way to export visio shape data directly into a SharePoint list.
But we can export visio shape data to an excel sheet and then import the sheet into SharePoint as a list.
First please export visio shape data to excel according to this article. The article is exporting to a database, but you can choose an excel file that already exists. (If you don't have one, please create it first as it doesn't create the file automatically.)
Second, we can choose “From Excel” when we create the list in SharePoint Online. Then we can create the list according to Excel. You can refer to this article to create.
I hope this helps.
