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.
yes that part we knew that.In general we are asking can we get all the features in the workbook which already have in MS Excel?
No, not all the features, for example https://activities.uipath.com/docs/excel-set-range-color only is available with Excel Application Scope.
