Error due to Excel being used by another UIpath process

Hi @inyourgravity,

There are two types of excel activities in UiPath.

  1. Excel application Scope. Works in Foreground. If the Excel file is already open, then it takes the same excel file to work on.

  2. Workbook type.- Works in Background. Throws exception in case Excel file is already Open
    In case you want to read an excel file, even if it is open then please use “Excel application Scope” activities i.e the activities which come under “Excel” category in Activities panel.

Reference : Read range after write cell

I hope this will be helpful.
