I'd like to render an excel workbook (specifically a pivot table) using Excel Services on our department's internal website and I am not sure how to do it (and I guess I am not searching correctly on Google, because I am not seeing what I want there either). We are using SharePoint 2013 and I have a page on a subsite that uses Excel Services to render a pivot table that connects to an external database.
A little more than a decade ago I made a web page that used Office Web Components to include a pivot table in web page I made and that is what I want (but I cannot use OWC because that was discontinued by Microsoft and I read that Excel Services is Microsoft's designated replacement for Office Web Components).
Right now I can create an iframe on our internal website that points at the page on our sharepoint server but I get all the sharepoint menus and headers in the iframe which is not what I want. Maybe the solution is to just to hide all the sharepoint stuff outside of the Excel Services rendering (but I do not know how to do that) or maybe there is a way to include that Excel Web Access web part in external web pages (also do not know how to do this). Any help pointing me in the right direction would be much appreciated!
