Question

我正尝试使用python 2.7版本将csv转换为xlsx，但它给我类似的错误

Traceback (most recent call last):
  File "C:/Users/XYZ/Desktop/converter.py", line 13, in <module>
    ws.cell(row=r, column=c).value = val
  File "C:\Python27\lib\openpyxl\cell\cell.py", line 291, in value
    self._bind_value(value)
  File "C:\Python27\lib\openpyxl\cell\cell.py", line 190, in _bind_value
    value = self.check_string(value)
  File "C:\Python27\lib\openpyxl\cell\cell.py", line 149, in check_string
    value = unicode(value, self.encoding)
UnicodeDecodeError: 'utf8' codec can't decode byte 0x93 in position 1037: invalid start byte

我的代码是

import os
import glob
import csv
import openpyxl 
for csvfile in glob.glob(os.path.join('.', 'i.csv')):
    wb = openpyxl.Workbook()
    ws = wb.active
    with open(csvfile, 'rb') as f:
        reader = csv.reader(f)
        for r, row in enumerate(reader, start=1):
            for c, val in enumerate(row, start=1):
                ws.cell(row=r, column=c).value = val
    wb.save(csvfile + '.xlsx')

下面是CSV文件名i.csv 受影响的平台列名称和1行单元格数据。

您可能已经使用Windows编码保存了文件，例如 unicodecsv library的用法如下：

import os
import glob
import unicodecsv as csv
import openpyxl 

for csvfile in glob.glob(os.path.join('.', 'i.csv')):
    wb = openpyxl.Workbook()
    ws = wb.active
    print csvfile
    with open(csvfile, 'rb') as f:
        reader = csv.reader(f, encoding='windows-1252')
        for r, row in enumerate(reader, start=1):
            for c, val in enumerate(row, start=1):
                ws.cell(row=r, column=c).value = val
    wb.save(csvfile + '.xlsx')

对于您提供的单元格，这将导致单个单元格包含多行。如果您想将此类条目转换为多个单元格，则需要进一步处理。为此，将需要一个更好的示例CSV文件。

例如，以下内容可用于删除HTML <br />标记：

ws.cell(row=r, column=c).value = val.replace('<br />', '')
