You can read both excel’s and store the data in their respective data tables like dt1 and dt2. Use merge data table activity to merge the dt1 as source and dt2 as destination under property field.

Use write range activity to create excel with dt2.

Hi @syaheed22,

Can you be more specific , what do you mean by same data.

Suppose first excel have 5 rows and second excel has 3 rows, do you want to combine in 3rd excel and want to have 8 rows, please specify your requirement clearly.

its actually, i want only same primary key in dt1 and dt2…
1 abc
2 def
3 ghi

1 abc
3 ghi
4 jkl

output i want:
1 abc
3 ghi


You can use for each row activity for iterating through all rows.

Flow should be like :

  1. Create data table dt3 using build data table.
  2. For each row for dt1.
  3. For each row for dt2.
  4. If condition to compare the value of primary key.
  5. If both are same, then use add row activity to dt3.

At last, you’ll have only rows in dt3 with same primary key. Use write range activity to create output excel with dt3.

Let me know if you have any questions.

why it said the column name not exist?
is it correct condition?
dt2.Select(“[aa no]='”+row1.item(“aa no.”).tostring+“'”)


If the above condition is to compare the primary key for both dt’s , then it should be like

row2(“aa no”). ToString.equals(row1(“aa no.”). ToString)

option strict disallow implicit conversion string to integer. i have no idea rn


If possible, can you please share screenshot of that part where this message appeared.
