Hi,
In recent version (at least 2012.12), there is a case something wrong around UiPath.Excel or UiPath.Excel.Helpers namespace. For example, the following error occurs when use UiPath.Excel.Helpers.ExcelUtilities.ConvertColumnLetterToColumnIndex method.
I did some tries such as importing UiPath.Excel.Helpers manualy, replace new activity , restarting Studio etc, the problem is solved for some reason… (However when I create a new project, there is same issue.)
Regards,
