excelでの汎用的な利用に関して(計算式コピー):On general use in excel (formula copy)

excel

#1

excelで最終行の次の行にデータを貼り付けます。
青色のセルの範囲
その後、計算式を貼り付ける前の最終行のセルを利用してコピーして貼り付けたいと思います。
貼り付け元:D3:E4
貼り付け先:D4:E6
緑色のセルの範囲

invoke codeを利用してこのような処理を汎用的に利用と考えています。
vb.netの知識なく頓挫しています。
AからC:データエリア
DからE:計算式エリア

uipathでの実現方法ご教示いただければと思います。

Paste the data on excel to the next line after the last line.
Range of blue cells
After that, I would like to copy and paste using the last row of cells before pasting the calculation formula.
Pasting source: D3: E4
Pasting destination: D4: E6
Range of green cells

We use invoke code to consider such processing as general purpose.
I am abandoned without knowledge of vb.net.
A to C: Data area
D to E: calculation formula area

I think that you can teach how to realize with uipath.excel
