Question

I\'m looking for the best approach for inserting a row into a spreadsheet using openpyxl.

Effectively, I have a spreadsheet (Excel 2007) which has a header row, foll

I took Dallas solution and added support for merged cells:

    def insert_rows(self, row_idx, cnt, above=False, copy_style=True, fill_formulae=True):
        skip_list = []
        try:
            idx = row_idx - 1 if above else row_idx
            for (new, old) in zip(range(self.max_row+cnt,idx+cnt,-1),range(self.max_row,idx,-1)):
                for c_idx in range(1,self.max_column):
                  col = self.cell(row=1, column=c_idx).column #get_column_letter(c_idx)
                  print("Copying %s%d to %s%d."%(col,old,col,new))
                  source = self["%s%d"%(col,old)]
                  target = self["%s%d"%(col,new)]
                  if source.coordinate in skip_list:
                      continue

                  if source.coordinate in self.merged_cells:
                      # This is a merged cell
                      for _range in self.merged_cell_ranges:
                          merged_cells_list = [x for x in cells_from_range(_range)][0]
                          if source.coordinate in merged_cells_list:
                              skip_list = merged_cells_list
                              self.unmerge_cells(_range)
                              new_range = re.sub(str(old),str(new),_range)
                              self.merge_cells(new_range)
                              break

                      "(\$?[A-Z]{1,3})%d"%(old),
                      lambda m: m.group(1) + str(new),
                      source.value
                    )
                  else:
                    target.value = source.value

                for c_idx in range(1,self.max_column):
                  col = self.cell(row=1, column=c_idx).column #get_column_letter(c_idx)
                  #print("Clearing value in cell %s%d"%(col,row))
                  cell = self["%s%d"%(col,row)]
                  cell.value = None
                  source = self["%s%d"%(col,row-1)]
                  if copy_style:
