通过excel复制，重新生成一个新的excel实现：
import copy
import openpyxl
from openpyxl.utils import get_column_letter
path = "数据.xlsx"
save_path = "数据-复制.xlsx"
wb = openpyxl.load_workbook(path)
wb2 = openpyxl.Workbook()
sheetnames = wb.sheetnames
for sheetname in sheetnames:
print(sheetname)
sheet = wb[sheetname]
sheet2 = wb2.create_sheet(sheetname)
# tab颜色
sheet2.sheet_properties.tabColor = sheet.sheet_properties.tabColor
# 开始处理合并单元格形式为“(,)，替换掉(,)' 找到合并单元格
wm = list(sheet.merged_cells)
if len(wm) > 0:
for i in range(0, len(wm)):
cell2 = str(wm[i]).replace('(,)', '')
sheet2.merge_cells(cell2)
for i, row in enumerate(sheet.iter_rows()):
sheet2.row_dimensions[i+1].height = sheet.row_dimensions[i+1].height
for j, cell in enumerate(row):
sheet2.column_dimensions[get_column_letter(j+1)].width = sheet.column_dimensions[get_column_letter(j+1)].width
sheet2.cell(row=i + 1, column=j + 1, value=cell.value)
# 设置单元格格式
source_cell = sheet.cell(i+1, j+1)
target_cell = sheet2.cell(i+1, j+1)
target_cell.fill = copy.copy(source_cell.fill)
if source_cell.has_style:
target_cell._style = copy.copy(source_cell._style)
target_cell.font = copy.copy(source_cell.font)
target_cell.border = copy.copy(source_cell.border)
target_cell.fill = copy.copy(source_cell.fill)
target_cell.number_format = copy.copy(source_cell.number_format)
target_cell.protection = copy.copy(source_cell.protection)
target_cell.alignment = copy.copy(source_cell.alignment)
if 'Sheet' in wb2.sheetnames:
del wb2['Sheet']
wb2.save(save_path)
wb.close()
wb2.close()
print('Done.')
