将文件合并为一个 Excel 文件

Question

我是 python 的新手，我认为这是一项简单的任务。我有一堆测试数据的文本文件，我想将它们合并到一个 Excel 文件中，每个文件都有不同的工作表。我所能完成的就是为每个文本文件制作单独的 Excel 文件。我尝试了很多方法来组合它们，但没有任何效果。我所做的最多的事情是用不同的工作表制作一个 Excel 文件，但数据不会传输。任何帮助深表感谢。

下面是我正在阅读的文本文件示例（/t = 制表符，/n = 新行，不在实际文本文件中）：

测试人员姓名：/t 姓名
测试日期：/t 14/18/1900
测试开始时间：/t 00:00:00 PM
测试结束时间：/t 00:00:00 PM
电压 (V) /t 旋转位置 (Deg) /t 力 (N)

-0.031 /t 0.000 /t -0.030 /n
-0.028 /t 0.000 /t -0.027 /n

下面是更新了 ClickProcessButton(self) 部分的完整代码。我确实意识到许多导入对于这个脚本是无用的。

                                else:
                                    worksheet.write(row, col, value)
                # except:
                #     pass
                except:
                    "*.xlsx" in file
            workbook.save('all_files.xlsx')

root = Tk()
app = Window(root)
root.wm_title("Tkinter button")
root.geometry("320x200")
root.mainloop()

此脚本在 workbook.save('all_files.xlsx') 行收到以下错误。错误是：IndexError：列表索引超出范围

您可以使用 pandas 和 ExcelWriter 来创建您想要的 Excel 输出。我假设您的文件存储在名为 test:

的文件夹中

import pandas as pd
import os

writer = pd.ExcelWriter('all_files.xlsx', engine='xlsxwriter')

for f in os.listdir('test'):

    header_info = pd.read_csv(os.path.join('test', f), sep=r'\t', engine='python', header=None, nrows=4)
    header_info.to_excel(writer, f, index=False, header=False)

    df = pd.read_csv(os.path.join('test', f), sep=r'\t', engine='python', header=4)
    df.to_excel(writer, f, startrow=5, index=False)

writer.save()
