Check if you have all of the required references listed in the Open XML SDK for Microsoft Office. You may also need to add a binding redirect in the Web.config file of the application through a piece of code like (when using DocumentFormat.OpenXml version 2.5.5631.0) :
For more information, you can refer to Missing DOCX, XLSX, PPTX, XPS export options KB Article.
Note also that there is a known issue with our latest official release (188.8.131.52) described in the Telerik Reporting R1 2019 fails to load assembly DocumentFormat.OpenXml 2.7.2+ KB article.
In case someone comes to this post in the future wondering how to make it work in an ASP.NET Core 3.1 app, I finally found (after many attempts) the Telerik support article with the answer:
then scroll down to the "Add the required dependencies" and you'll find the answer on item #2:
Optionally, for export to Office OpenXML document formats (XLSX, DOCX and PPTX) install the Telerik.Reporting.OpenXmlRendering (or Telerik.Reporting.OpenXmlRendering.Trial) NuGet package and the DocumentFormat.OpenXML NuGet package version 184.108.40.206 and above.
