Hi Jason,
Greetings from Syncfusion.
As of now, we don’t have support to export multiple controls as excel. We have excel export for grid control. Please check with the below documentation and online demo link.
We have already logged a feature request on chart excel export. Based on other logged tasks priority, this feature will be included in any of our upcoming release. You can keep track of the feature from the feedback portal below.
If you have any more specification/precise replication procedure or a scenario to be tested, you can add it as a comment in the portal.
Regards,
Durga G
