Dhtmlx gantt export to excel tasks hierarchy issue

HI,

When i download excel file by using below method.
gantt.exportToExcel();

Excel file missing tasks hierarchy. Please anyone give input on this.

Hello Anuj,
Thank you for reporting about the issue.
Looks like, there is the tree structure if you open the file in Microsoft Excel, but you won’t see that in Libre Office. I added the bug in the tracker, and the dev team will fix it in the future, but I cannot give you an ETA.

Could you clarify which Office program do you use to open the file?

Hello Anuj,
The dev team fixed the bug Excel files didn’t have the tree structure if you opened them in Libre Office.

You can check how it works in the following sample:
