I have 2 excel worksheets as inputs I am trying to join on same key element. These two have exactly same number of rows and same column headers. I need to compare the values of each column for both data inputs. For this I need the same columns to be placed next to each other. for example, the 2 sheets have columns as field1, field2, field3.. field 100. and workbook 2 has same fields field1, field2, field3.. field 100. i need my output to have columns as field1, field1_right, field2, field2_right, field3, field3_right... and so on.
