Excel delete row

I want to delete rows from excel file which haveng the number less than 4.I used remove data row activity but after some iteration it throw an error of index.
The column contains the nos(ex. 1,2.5,4.9,5)

@ImPratham45 read your excel and assign output to datatable variable.
Using select based on ur column check for values which is more than 4, assign that output to new datatable. write new datatable new excel sheet.

Ty but I got an answer by another way actually i wanted to write it in main excel only.
