Support for ProjectSheet for Excel
There is a Free version with WBS breakdown and Gantt chart and a Pro version that also includes task duration and dependencies, resource assignment and cost calculation. See screenshot below for ProjectSheet Pro for Excel.

The Pro version requires to sign in with your Microsoft account in the app and to register for a free 10-day Pro trial or a 1-year license for €24/year (excl. VAT). Without a Pro license, you will keep your schedules with Free version functionality to continue.
