Check below post for your reference

Linq query for groupby and sum

@Sugumar8785 in that case I would suggest [grafik] [grafik] [grafik] Groups = (From dte In dtData.AsEnumerable Group dte By col1=dte(2).ToString.Trim Into grp=Group Select grp.toList).toList for Key Columns: grp.First()(KeyColumnNameOrIndex) for Aggregations e.g Sum: grp.Sum(Function (x) CInt(x(ColIndexOrName).toString.Trim)) This split allows you a more control on bug fixing and maintenance

But this will differ according to your excel data and your logic
