Auto fill range variable


Please, could you help me

I need to use auto fill range but the end of the line is always variable.
example I need to pull formulas from cells A2: up to H but I don’t know the line number.

Hi @LucasSilva!

What I usually do when I face this issue is first use a ReadRange activity to retrieve that data, thus allowing me to know how many rows there are.

Then in the auto fill range you would just do: "A2:H" + (dt.Rows.Count + 1).ToString where dt is the variable with the result of read range, and +1 is because your rows with data start from the second row of the Excel.


Hi @nerlichman,

The error below appears


Can you check the value of dt.Rows.Count and which is the last row in you example?

You need to show the details of the error, for better understand of the problem.

The destination must include the source range in the auto fill range… and it must go to one direction only, line or column…


It worked, I had forgotten that detail.
Thank you very much
