Hi @ASWATHY_K ,

Have you tried using the Filter Datatable activity ?

Let us know if this does not meet your requirements and maybe explain a bit more as to what is needed.

i wanted the headers also

@ASWATHY_K ,

The Filter Datatable activity should also preserve the Headers in the Datatable.

Let us know after you have tried and if the headers are not being preserved.
