Concatenate two columns from Excel Table

I want Write a productcode Like these “12A-2123” any one tell me how to write a code

Hi @killarapusiva

I assume by product code you mean a concatenation of column product and a substring of column code. In that case, loop over each row, and set Row("product code") = Row("product").Trim + "-" + Row("code").Trim.Substring(4,4)

Like this:

Alternatively, you can do the same by reading the sheet into memory, using a For Each Datarow activity, and then rewriting the sheet into Excel with a Write Range.

Kind Regards

Hi @killarapusiva

Your steps would be as follows below

Read range the excel using excel read range

For each row in readDt


Currentrow(“Productcode”) = currentRow(“Product”).toString+"-"+Currentrow(“Code”).tostring.substring(Currentrow(“Code”).tostring.Length-4)

Out side the Loop

Write range with same path,sheet,datatable as readrange



Assign:- Counter=1 ->Int32 variable

use write cell activity-> Value->


Range in write cell: “D”+(Counter+1).ToString

Assign:- Counter=Counter+1



Have a look here:

the concatenation is a good case matching to the Datacolumn.Expression approach

Nice, never knew about the DataColumn.Expression method.

Shame the article doesn’t include/compare execution time though.
