Hello @Shaughn Allen , Thanks for using Microsoft Q&A Platform.
I haven't completely understood your question please share more details with us. In document intelligence service we have models like Custom template to recognize signature from the documents but returns the response in the JSON format.
You can try some post processing techniques to extract the response to the excel as per your requirement.
Is this something you are looking for?
I hope this helps.
Regards,
Vasavi
