Question

首先，我是编程方面的新秀。

我正在尝试使用python3将MySQL数据库导出为excel格式。我正在使用openpyxl。现在我在excel中有一个有趣的错误。如果我运行代码，但是SQL查询很小（大约1000行），那么在查看excel时我不会出现错误，但是当我尝试打开excel时，如果它更大（> 30k行），则会出现错误：

error135840_01.xml在文件'C：\ Users \ id022504 \ PycharmProjects \ GetMySQLdata \ Interface planning _mau.xlsx'中检测到错误记录已删除：/xl/worksheets/sheet1.xml部分中的公式

当我使用Open XML SDK打开excel文件时，很有趣，它指出问题出在颜色上：

下面是代码：

import mysql.connector
import openpyxl
from openpyxl import Workbook
from openpyxl.styles import Border, Side, Font, Alignment
import datetime
import os
from openpyxl.worksheet import Worksheet

mydb = mysql.connector.connect(
  host="10.10.10.10",
  user="user",
  passwd="password"
)

#Funcao para por as colunas com auto size
def auto_column_resize(worksheet):
    for col in worksheet.columns:
         max_length = 0
         column = col[0].column # Get the column name
         for cell in col:
             try: # Necessary to avoid error on empty cells
                 if len(str(cell.value)) > max_length:
                     max_length = len(cell.value)
             except:
                 pass
         adjusted_width = (max_length + 2) * 1.2
         if adjusted_width <= 95:
            worksheet.column_dimensions[column].width = adjusted_width
         else:
             worksheet.column_dimensions[column].width =95
    return worksheet

Answer 1

我发现了问题，在其中一个单元格中出现了“ =”符号，并以某种方式将excel识别为公式。要解决该问题，我只需清理“ =“。

import re
try:
    new_ws_row[7].value = re.sub("=", "", new_ws_row[7].value)
except:
    pass
