Openpyxl 插入数据添加数据

pip install xlwt

程序循环多次，每次向指定的excel中追加写入数据

# 使用openpyxl追加写入数据到Excel
import openpyxl
import os
from openpyxl.styles import Alignment

def create_excel_xlsx(path, sheet_name):
    workbook = openpyxl.Workbook()
    sheet = workbook.active
    sheet.title = sheet_name
    header = ['id','sex','age','provience','job']
    sheet.append(header)
    alignment = Alignment(horizontal='center', vertical='center', wrap_text=True)
    sheet.alignment = alignment
    workbook.save(path)

def write_excel_xlsx_append(path, value, truncate_sheet=False):
    # 如果不存在就创建该excel
    if not os.path.exists(path):
        create_excel_xlsx(path, 'Sheet1')

    #value = value.values #将dataframe转为array
    data = openpyxl.load_workbook(path)
    # 取第一张表
    sheetnames = data.sheetnames
    sheet = data[sheetnames[0]]
    sheet = data.active
    if(truncate_sheet): #truncate_sheet为True，覆盖原表中的数据
        startrows = 0
    else:
        # print(sheet.title)  # 输出表名
        startrows = sheet.max_row  # 获得行数
    index = len(value)
    for i in range(0, index):
        for j in range(0, len(value[i])):
            sheet.cell(row=startrows + i + 1, column=j + 1, value=str(value[i][j]))

    #调整对齐
    alignment = Alignment(horizontal='center', vertical='center', wrap_text=True)
    data.alignment = alignment
    data.save(path)
    print("xlsx格式表格追加写入数据成功！")

def read_excel_xlsx(path, sheet_name):
    workbook = openpyxl.load_workbook(path)
    # sheet = wb.get_sheet_by_name(sheet_name)这种方式已经弃用，不建议使用
    sheet = workbook[sheet_name]
    for row in sheet.rows:
        for cell in row:
            print(cell.value, "\t", end="")
        print()

book_name_xlsx = 'xlsx格式测试工作簿.xlsx'
sheet_name_xlsx = 'xlsx格式测试表'
value3 = [["1111", "女", "25", "石家庄", "运维工程师"],
          ["222", "男", "55", "南京", "饭店老板"],
          ["333", "女", "27", "苏州", "保安"], ]

write_excel_xlsx_append(book_name_xlsx, value3, False)
read_excel_xlsx(book_name_xlsx, 'Sheet1')
