python3结合openpyxl库实现excel操作的实例代码

import openpyxl
# 新建一个空excel，表名为sheet，文件名为test
wb = openpyxl.Workbook() # 创建新的excel文件，一个工作簿(workbook)在创建的时候同时至少也新建了一张工作表(worksheet)
wb.save('test.xlsx')

import openpyxl
import openpyxl.styles
# 打开已有的excel
wb = openpyxl.load_workbook("test.xlsx")
# ------------------ 表操作 ------------------
# 新建sheet表
wb.create_sheet(index=2, title="sheet3") # 可通过index控制创建的表的位置
# 获取所有表名
sheet_names = wb.sheetnames # 得到工作簿的所有工作表名 结果： ['Sheet1', 'Sheet2', 'Sheet3']
# 根据表名删除sheet表
wb.remove(wb[sheet_names[2]]) # 删除上一步建的第3个工作表
# 根据表名打开sheet表
sheet1 = wb[sheet_names[0]] # 打开第一个 sheet 工作表

# ------------------ 读取数据 ------------------
# 获取单元格数据
sheet1_max_colum = sheet1.max_column # 获取最大列数 结果：3
# ws = wb.active # 获取当前活动的sheet页
sheet1_max_row = sheet1.max_row # 获取最大行数 结果：10
A1_value = sheet1['A1'].value # 获取单元格A1值 结果：a1
A1_column = sheet1['A1'].column # 获取单元格A1列值 结果： A
A1_row = sheet1['A1'].row  # 获取单元格A1行号 结果： 1
A1 = sheet1.cell(row=1, column=1).value # 获取第一行第一列的单元格值 结果：a1
# 获取C列的所有数据
list_sheet1_column_C = []
for i in sheet1["C"]:
  list_sheet1_column_C.append(i.value)
# 获取第1行的所有数据
list_sheet1_row_1 = []
for i in sheet1[1]:
  list_sheet1_row_1.append(i.value)
# 读取所有数据
list_sheet1_all = []
for row in sheet1.rows:
  for cell in row:
    list_sheet1_all.append(cell.value) # 按行循环获取所有的值，保存在 list_sheet1_all 列表中

# ------------------ 写入数据 ------------------
sheet1.cell(row=1, column=2, value="B1") # 修改第一行第二列的单元格的值为B1
sheet1["A1"] = "A1" # 直接修改A1单元格的值为A1
sheet1["B11"] = "B11" # 新增B11单元格的值为B11
sheet1.title = "test_sheet" # 修改sheet1的表名为test_sheet

# ------------------ 表格样式调整 ------------------
# 表格样式支持：字体、颜色、模式、边框、数字格式等
# A1单元格 等线24号加粗斜体，字体颜色浅蓝色
sheet1["B11"].font = openpyxl.styles.Font(name="宋体", size=24, italic=True, color="00CCFF", bold=True)
# B1单元格 水平上下居中
sheet1["B11"].alignment = openpyxl.styles.Alignment(horizontal="center", vertical="center")
# 第一行高度设置为30
sheet1.row_dimensions[1].height = 30
# C列的宽度设置为35
sheet1.column_dimensions["C"].width = 35

# 保存文件，注意文件打开时文件保存会出错
wb.save("test.xlsx")
