How to process for each activity when the excel cell value equal to blank

Hi experts,

I have one excel file which need to process in the workflow system,
I want to use for each activity to process each rows which the value in the first column Workflow number = Blank,

as below sample, 2columns, User name and workflow number, row with workflow number 17999 and 18102 will not be processed, only process for rows of workflow number = blank, how to do this ?

User Name Workflow number
Joe 17999
Nancy 18102

Read the excl file, use for each row to loop thru all the rows, use if condition to check whether it is blank or not.

Refer the vedio tutorials for more details.

thanks! I have find solution for it
