import re


'''
file:文件目录的路径
text:需要替换的字符
replacetext:期望替换成的字符
'''

    ws = wb.sheet_by_index(0)  # 根据index获取sheet

    rows = ws.nrows
    cols = ws.ncols

    newbook = copy(wb)  # 复制xls
    newsheet = newbook.get_sheet(0)

    # 遍历每个单元格，进行替换操作
    for row in range(1, rows):

    # 保存新的xls以替换原有的xls
    newbook.save(file)
