How update excel (insert data row wise)?

Dear Team,

I need help to update excel sheet.

I have created flow in which I am able to paste data into excel in one row but I need to run script after every 30 minutes.

need to insert data in next row after every 30 minutes. “A” is fixed need to insert data from B2.

Below is the excel and flow screen shots.


When you open the excel file to set the table, you can save one of the columns, for example, B, to a List variable, get its size, and calculate the number of the row from which to start by adding 1 to it.
