Hi Olivier,
Thanks for using Syncfusion products.
By default, the Syncfusion components have the support to exporting into excel. We need some more details about your scenario, so please provide the below details which will help us to provide solution at the earliest
- A simple screenshot of structure of hierarchical layout as per your requirement (i.e., whether the hierarchical layout with diagram or grid control, or any others)
- Let us know which Syncfusion components you want to use in your sample project.
Regards,
