Get value from column header

Hello all,

How can I get value from column header as below. Thank all
Column A Dynamic Column DC DC DC DC
ITEM No. (MM),(OD X MM) - (PC),(PCS),(PCS.) - (KGS),(MT) - (USD/PCS) - AMOUNT

Hi @anh.nguyen,

Your question is not clear. Do you need all headers in string format?

If yes below expression would help.

Join(“,”(From dc In InputDt.Columns.Cast(Of DataColumn) Select dc.ColumnName).ToArray())

Anyone help me get value from the column header as below?

Hi @anh.nguyen ,

I assume you use activity read range with not providing specific range to read (“”).
For this case, you can yous below solution step :

  1. Read range activity with no range “” and output variable is DtRead
  2. Use Assign activity and create variable (GenericValue/Integer) CountDataRange = DtRead.Rows.Count.ToString
  3. Use Assign again CountDataRange=CountDataRange+1
  4. Use Read Range with range “A2:X”+CountDataRange.ToString
  5. Try to check output from step no 4.

It copy all INV sheet, I just copy data from row have Cellname: “Item No.” to lastrow of table

Hi @anh.nguyen ,

In that case you can read range no 4 with “A2:A”+CountDataRange.ToString



  1. put all the column headers you want in a list e.g. filterList (this can be a dynamic list)
    e.g. {“item no.”, “discription of goods (mm)”, “quantity(pc)”…}

  2. read datatable from excel e.g. to variable called dt

  3. assign New DataView(dt) to a dataview variable
    assign dataView.ToTable(false, filterList.ToArray) to filteredTable variable

now your filteredTable variable will be a table with only columns you want!

Hi @aliaga
Sorry I not explain clearly, my mean copy for Cellname" ITEM No." to last row (col R or AZ…) but last Col has title AMOUNT

can you just standardize all the columns to be the same

do foreach loop on dt.copy.columns

  • if column.columnNname.contains “Discription” then assign
    dt.Columns(currentItem.ColumnName).ColumnName = "Discription"

and so on…

so now your columns will be the same “DISCRIPTION OF GOODS”, “QUANTITY” etc…
