Hi Ranjan,
Thank you for your interest in Syncfusion products.
We regret to let you know that we don’t have separate
support for optimized excel filter wired with Child table or Child groups. For
more details, Please create a DT incident for better follow up.
You can create the DT incident from the following link.
