Question

使用openpyxl，我试图从Excel工作簿中读取数据并将数据写入同一个Excel工作簿。从Excel-Workbook获取数据工作正常，但将数据写入Excel-Workbook不起作用。使用下面的代码，我从A1中的单元格Sheet1获取值并打印出来。然后我尝试将一些值放入单元格A2和A3。这不起作用。

from openpyxl import Workbook
from openpyxl import load_workbook


wb = load_workbook("testexcel.xlsm")
ws1 = wb.get_sheet_by_name("Sheet1")

#This works:
print ws1.cell(row=1, column=1).value 

#This doesn't work:
ws1['A2'] = "SomeValue1"

#This doesn't work either:
ws1.cell(row=3, column=1).value = "SomeValue2"

我确信代码是正确的......这里出了什么问题？

Answer 1

我相信你错过了保存功能。尝试添加以下附加行。

from openpyxl import Workbook
from openpyxl import load_workbook


wb = load_workbook("testexcel.xlsm")
ws1 = wb.get_sheet_by_name("Sheet1")

#This works:
print ws1.cell(row=1, column=1).value 

#This doesn't work:
ws1['A2'] = "SomeValue1"

#This doesn't work either:
ws1.cell(row=3, column=1).value = "SomeValue2"

#Add this line
wb.save("testexcel.xlsm")

Answer 2

用它来写一个值：

ws1.cell(row=1, column=1,value='Hey')

另一方面，以下内容将读取值：

ws1.cell(row=1, column=1).value

使用openpyxl将数据写入Excel工作表并不起作用
