检查代码错误import unicodedata from openpyxl import load_workbook # 指定表格文件名列表 filenames = ['统计.xlsx'] # 使用列表推导式读取多个表格 workbooks = [load_workbook(filename) for filename in filenames] # 遍历每个工作表 for workbook in workbooks: for sheetname in workbook.sheetnames: sheet = workbook[sheetname] # 遍历每个单元格 for row in sheet.iter_rows(): for cell in row: # 判断单元格是否为字符串类型 if isinstance(cell.value, str): # 将全角字符转换为半角字符 cell.value = unicodedata.normalize('NFKC', cell.value) # 保存修改后的 Excel 文件 for i, workbook in enumerate(workbooks): filename = filenames[i].replace(".xlsx", "-1.xlsx") workbook.save(filename)

你的代码有一个语法错误。在 `import` 语句中，你需要使用 `as` 关键字来指定 `unicodedata` 模块的别名，如下所示：

import unicodedata as ud
from openpyxl import load_workbook

# 指定表格文件名列表
filenames = ['统计.xlsx']

# 使用列表推导式读取多个表格
workbooks = [load_workbook(filename) for filename in filenames]

# 遍历每个工作表
for workbook in workbooks:
    for sheetname in workbook.sheetnames:
        sheet = workbook[sheetname]
        
        # 遍历每个单元格
        for row in sheet.iter_rows():
            for cell in row:
                # 判断单元格是否为字符串类型
                if isinstance(cell.value, str):
                    # 将全角字符转换为半角字符
                    cell.value = ud.normalize('NFKC', cell.value)

# 保存修改后的 Excel 文件
for i, workbook in enumerate(workbooks):
    filename = filenames[i].replace(".xlsx", "-1.xlsx")
    workbook.save(filename)

这样修改后应该就可以正常运行了。
