Hi Steve,

In Blazor, you can't get the template contents in code, and so templates are not exported. You can read more about this and some other information that might be useful about the way exporting works in the Notes section of its article.

Thus, what we do is we render the defined aggregates for the given field after their name. You can see how this works with the code snippet that I am attaching to this post, and I am also adding the resulting Excel file as reference.

With that said, since this is a limitation stemming from the framework, I am marking this as "Declined" which means "Not a valid feature request or bug report" - there simply is no way for us to achieve this.

Regards,
