【Python】Excel表格操作：ISBN转条形码

一、效果

二、代码

import os
import logging
from openpyxl import load_workbook
from openpyxl.drawing.image import Image as ExcelImage
from barcode import EAN13
from barcode.writer import ImageWriter

logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')

    logging.info("开始处理")

    if not os.path.exists('barcode_temp'):
        os.makedirs('barcode_temp')

    wb = load_workbook(excel_file)
    ws = wb.active
    logging.info(f"加载工作表: {ws.title}")

    img_height_in_points = 45  # 你设置的图片高度，单位是磅，1磅约等于1.33像素

    for row in range(2, ws.max_row + 1):
        barcode_cell = ws.cell(row=row, column=ISBNCol)
        barcode_str = str(barcode_cell.value).strip()
        if not barcode_str or len(barcode_str) != 13 or not barcode_str.isdigit():

        except Exception as e:
            logging.error(f"生成条码失败，行{row}，条码{barcode_str}，错误: {e}")

        img_cell = f'{imgCol}{row}'

        # # 设置列宽
        ws.column_dimensions[imgCol].width = img_for_excel.width * 0.15
        # # 设置行高
        ws.row_dimensions[row].height = img_for_excel.height

        ws.add_image(img_for_excel, img_cell)

    if os.path.exists('barcode_temp'):
        logging.info("删除临时文件")
        delete_files('barcode_temp')

    logging.info("完成处理！")


if __name__ == "__main__":
    excel_path = 'D:\\temp\\图书清单.xlsx'
    insert_barcodes_to_excel(excel_path, 1, "B")

三、说明

1、insert_barcodes_to_excel参数1：原始Excel表格文件绝对路径。

2、insert_barcodes_to_excel参数2：ISBN所在列，数字格式。例如：ISBN在A列则输入1，在B列则输入2。

3、insert_barcodes_to_excel参数3：生成的条形码需要放在第几列，大写字母格式。例如：需要放在第二列则输入B，第三列则输入C。
