Hey @Rowley101, You can use delete range activity and provide the input lets say “A1:B7”

Hope this will help!

If you’re deleting from excel, use the above solution.

If it is a DT with another source in the workflow, there are several options:

  • Loop through your DT and determine if the row that’s been presented is an applicant for deletion baserd on either content or an index # if that is applicable
  • use filter datatable to remove them, if you can describe your range by a condition
  • if you simply know that you need to remove row number n1 to n2, make a loop that runs from n1 to n2 and call the ‘remove data row’ activity, passing the n value as index.

Hi @Rowley101

You can use invoke code activity using this syntax

Datatable_variable.Rows.RemoveAt(Index_of_the_row)

Fine if you know the number of rows to delete then we can try with skip or take method

Like this in a simple assign activity

dt = dt.AsEnumerable().Skip(20).CopyToDatatable()

Or with take method

dt = dt.AsEnumerable().Take(20).CopyToDatatable()

Skip will remove the mentioned number of records from the first row and gives the remaining

Take will give only the mentioned number of rows from DATATABLE

Cheers @Rowley101

in case of we want to take or from start we can use take or skip as mentioned by Palani

we also can chain it:

in case of we want to remove an inner range out of the datatable we can do work with concat or indexed Where LINQ:
