thanks in advance.


Follow the steps

  1. Use for each row in excel activity
  2. Use for each activity with In argument as Enumerable.Range(0,48).ToArray
  3. Then inside the loop use if condition with currentrow.ByIndex(currentitem).ToString.Trim.Equals(String.Empty)
  4. On then side use set range color activity or format cels activity and use the color and give range as Excel.Sheet("sheetname").Range(currentrow.ByIndex(currentitem).Address)

I just modified your sample. Can you try the following?

Sequence1.xaml (14.3 KB)



What I gave you are the details using excel for each row activity…But I see you read the data and use for each row in datatable…so I modified it as per your logic only…Mode few changes as per the activities you used (9.7 KB)


Indexval is the variable assigned to the index property in for each row in datatable…added 2 because 1 for index starting from zero and other for the header. Also have added dt.Columns.Count instead of 48 to make it dynamic for any number of columns

My method is depicted by @Yoichi above , you can try that as well…not much of difference…main is in your’s read the data into datatable in the formers which I provided it uses data directly from excel
