I am looking at your website and it looks like you have SDKs or REST APIs in order to manipulate documents.
I am designing an Enterprise Search Solution and one of the most complex things to develop, we call it the anonymization engine.
Basically we need to remove Text from PDFs, Word Files, and Maybe excel files. Based on criteria we will configure in another application.
Is this something your software would allow me to do?
Apparently the sales department cant answer this 
Yes, Aspose provides both on-premise APIs and Cloud SDKs/REST APIs for document manipulation.
You can replace text in the DOCX, PDF and Excel documents using Aspose.Words Cloud, Aspose.PDF Cloud and Aspose.Cells Cloud APIs respectively as following.
DOCX:
PDF:

Excel:
