Can we perform UIPath tasks without microsoft office?

We don’t have Microsoft office in our individual systems and we have Open Office only. So can we perform the UIPath tasks using open office or MS Office is mandatory?

Depends on what you want to do. For example, Excel Appliction scope can work without office, and also, you can use Workbook activities.

No, not all the features, for example only is available with Excel Application Scope.
