from openpyxl import load_workbook
from PIL import Image
wb = load_workbook("test.xlsx")
ws = wb[wb.sheetnames[0]]
for image in ws._images:
    # 输出图片的位置信息
    # 列号
    col = image.anchor._from.col
    # 行号
    row = image.anchor._from.row
    print(type(col))
    print(row)
    img = Image.open(image.ref)
    path = "%s-%s.png" % (col, row)
    # 保存图片
    img.save(path)
wb.close()
