Hello Vignesh,
Good Day.!
Would it be possible for you to mention the version of the package ‘UiPath.Excel.Activities’ you are using in your project?
Thanks,
Gautham.
You are using the right activity. Under What to Write pass the datatable variable and where to write pass WBS.Sheet("Sheet1").
Hope it helps
The version of excel package is V2.22.3
Hey vignesh,
Can you check if ‘Write range workbook’ activity in activities pane.?
Thanks,
Gautham.
