非常抱歉，我之前的回答中有一个错误。在 `sheet.iter_rows()` 返回的是一个字符串列表，而不是一个具有 `row` 属性的对象。因此，在这里需要使用索引来访问行号。请将以下代码进行修改：for row_index, row_values in enumerate(sheet.iter_rows(min_row=2, values_only=True), start=2):
cell_value = row_values[column_number - 1] # 列索引从1开始，故需减1
converted_value = convert_cell_format(cell_value, cell_format)
sheet.cell(row=row_index, column=column_number + 2, value=converted_value)

from tkinter import Tk, filedialog
from tkinter import ttk

def open_workbook(file_path):
if file_path.endswith('.xlsx'):
return openpyxl.load_workbook(file_path)
else:
raise ValueError('Invalid file format')
def get_sheet_names(workbook):
if isinstance(workbook, openpyxl.Workbook):
return workbook.sheetnames
else:
raise ValueError('Invalid workbook type')
def get_column_names(sheet):
if isinstance(sheet, openpyxl.worksheet.worksheet.Worksheet):
column_letters = list(sheet.columns)
column_names = [col_letters[0].column_letter for col_letters in column_letters]

def convert_cell_format(cell_value, cell_format):
if cell_format == '文本':
if isinstance(cell_value, (int, float)):
return str(cell_value)
else:
return cell_value
elif cell_format == '日期':
if isinstance(cell_value, str):
return datetime.datetime.strptime(cell_value, '%Y-%m-%d').date()
else:
return cell_value
elif cell_format == '数值':
if isinstance(cell_value, str) and cell_value.isdigit():
return int(cell_value)
