将多个 csv 合并到单个 xslx 的脚本不起作用

Question

我已经阅读了所有与此相关的主题，但我仍然陷入了死胡同。只是尝试将目录中的所有 csv 文件作为新工作表添加到新的 xlsx 工作簿中。这是我得到的：

import xlwt, csv, os, glob

def make_excel_workbook(path):
    wb = xlwt.Workbook()
    for filename in os.listdir(folder_path):
        if filename.endswith('.csv'):
            ws = wb.add_sheet(os.path.splitext(filename)[0])
            with open('{}\{}'.format(folder_path, filename), 'rb') as csvfile:
                reader = csv.reader(csvfile, delimiter=',')
                for rowx, row in enumerate(reader):
                    for colx, value in enumerate(row):
                        ws.write(rowx, colx, value)
    return wb

csvDir = "C:\Temp\Data\outfiles"
outDir = "C:\Temp\Data\output"

os.chdir(csvDir)
csvFileList = []
searchTerm = "character string"

for file in glob.glob('*.csv'):
    csvFileList.append(file)

for i in csvFileList: # search a set of extant csv files for a string and make new csv files filtered on the search term
    csv_file = csv.reader(open(i, 'rb'), delimiter=',')
    rowList = []
    for row in csv_file:
        for field in row:
            if searchTerm in field:
                rowList.append(row)
    outputCsvFile = os.path.join(rootDir, i)
    with open(outputCsvFile, 'wb') as newCsvFile:
        wr = csv.writer(newCsvFile, quoting=csv.QUOTE_ALL)
        wr.writerows(rowList)

到目前为止，它可以工作，并从原始的、更大的文件创建新的 csv 文件。这是中断的地方：

if __name__ == '__main__':
    xls = make_excel_workbook(outDir)
    xls_name = "My_Team_Tasks"
    xls.save('{}\{}{}.'format(outDir, xls_name, '.xls'))
    print('{}\{}{} saved successfully'.format(outDir, xls_name, '.xls'))

当它到达 xls.save 时，出现以下错误：

更新：这是整个回溯：

        xls.save('{}\{}{}'.format(rootDir, xls_name, '.xls'))

        us = unicode(s, encoding)

Answer 1

您知道输入的 CSV 文件是如何编码的吗？从错误信息看来是 unicode?

你可以试试：

wb = xlwt.Workbook(encoding='utf-8')

否则，根据此答案 (xlwt module - saving xls unicode error)，解决此问题的另一种可能方法是在写出之前将您的文本编码为 unicode。

ws.write(rowx, colx, value.decode('utf-8'))

同样，这取决于您输入的编码方式。
