Calculate average of similar rows cell in Excel

Hi ,

How can we calculate the average of 2 similar rows cells in Excel using UiPath
Suppose: I have an excel and its 2 rows first cells are similar and we want the average of 2 cells beside the first cells in different excel sheet.
Input Value
A1 23.9
A2 18.7
A1 24.9
A2 16.8

A1 Avg(23.9,24.9)
A2 Avg(18.7, 16.8)


please try Write cell activity with below formula

Let me know if that works.

this A1 and A2 are present in the same sheet and can be anywhere maybe cell A11 contains A2 and cell A1 contains A2
A1 and A2 are not cell numbers they are random item names like a1,a2,a3…

any suggestion guys on this??


Read Range the sheet, and find the unique and loop those values to sum and average!

Below is the error on running your workflow i got:
Assign : Column ‘Header1’ does not belong to underlying table ‘’

and i am getting this error
Assign : Object reference not set to an instance of an object.


make sure you have Excel path updated in excel read range activity.


I used Read Range activity of the workbook .Updated the path and now I got this error.’
Assign : Column ‘Header1’ does not belong to underlying table

any suggestion on below query


make sure the column name in the excel input file, in the example i provided the column A i named as Header1

actually the excel is like this:
From “Heading1” column Bot has to remove “=” and fetch only the chars and no sign and for both a1 and a2 it has to calculate the average values of the values present in Column “Heading2”

Hi Saranya,
in my scenario,header1 contains multiple a1,a2,a3,…ath…the logic that u have provided is just for a1 and a2 to add in the collection…Please suggest how we will calculate if we have multiple time a1,a2,a3 and their corresponding values in header2


In this place of code, you can replace with Switch Activity if the number of header columns are known.
