xlwings error: not opening excel workbook getting an error upon call wb.open

Question

xlwings 在我的电脑上工作正常，但是当我尝试将相同的设置转移到另一台电脑时，它似乎无法正确打开并给我这个错误

这里是一些简化的代码，其中 none 的数据正在发生变化。使用 ospath absolute 对错误没有帮助。两个系统运行相同的 64 位操作系统和 32 位 excel。然而，错误仍然存在于第二台机器上。我可以理解没有真正的区别会给我在第一个系统上的第二个系统上的错误。两台机器都是PC

import xlrd
import openpyxl
import xlwings as xw
from xlwings import constants
import os
import tkinter as tk
from tkinter import filedialog

import datetime


root = tk.Tk()
root.withdraw()

file_path = filedialog.askopenfilename()
print(file_path)

start = time.time()


wb = openpyxl.load_workbook(file_path)
Returns = wb['Prices']
newWs = wb.create_sheet()
newWs.title = "NominalDailyReturns"

benchWS = wb.create_sheet()
benchWS.title = "ActiveDailyReturns"


thirdWs = wb.create_sheet()
thirdWs.title = "RawAnalysis"
thirdWs.column_dimensions["A"].width = 32

name4 = thirdWs.title


print("halfway")

print(os.path.split(file_path))
print("output" + timeName + os.path.split(file_path)[1])

wb.save("output" + timeName + os.path.split(file_path)[1])

xwWb = xw.Book(os.path.abspath("output" + timeName + os.path.split(file_path)[1]))
XnewWs = xwWb.sheets['NominalDailyReturns']

xwWb.save()
xwWb.close()

wb = openpyxl.load_workbook("output" + timeName + os.path.split(file_path)[1])
benchWS = wb['ActiveDailyReturns']

wb.save("output" + timeName + os.path.split(file_path)[1])
xwWb = xw.Book("output" + timeName + os.path.split(file_path)[1])

XthirdWs = xwWb.sheets['RawAnalysis']
xwWb.save()
xwWb.close()

Answer 1

我发现了我的代码的问题。当我使用 openpyxl 编辑我的 excel 数据时，其中一个公式是从数字中减去一个单词，引发错误并损坏 excel 文件。然后 xlwings 试图打开一个损坏的文件，但我失败了。

所以解决方案是不保存损坏的 excel 文件并期望 xlwings 打开它。

xlwings error: not opening excel workbook getting an error upon call wb.open

xlwings error: not opening excel workbook getting an error upon call wb.open

python

winapi

pywin32

python-3.x

xlwings
