    row_idx += 1

# Iterate over the DataFrame and write to the sheet from the first empty cell onwards

Trying to paste a dataframe into an existing excel sheet, but for some reason, even after specifying, it just pastes in the same cell as always, which will be cell A6 in the excel sheet. Am i missing something? Thanks a lot.
