Good day Erich.
Tableau has the ability to be embedded into existing websites. Here is a help document from Tableau detailing a few ways to get the embed code for a published workbook. This assumes you're using a Tableau Server, Tableau Online, or possibly Tableau Public to host your workbook.
(Note while Tableau Public is free, it is also really really public! Anything you publish to Tableau Public will be available to everyone in the world).
Does this help? You didn't mention whether you have the ability to publish either to Tableau Server, Tableau Online, or Tableau Public. If you're using Desktop without only it's going to be much more limited.
