将文件合并为一个Excel文件

Question

我是python的新手，我想这是一个简单的任务。我有一堆测试数据的文本文件，我想合并为一个Excel文件，每个文件具有不同的工作表。我所能做的就是为每个文本文件制作单独的Excel文件。我尝试了很多方法将它们组合在一起，但是没有任何效果。我最忙的是制作带有不同图纸的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的示例（/ t =制表符，/ n =新行，不在实际的文本文件中：]

测试人员名称：/ t名称测试日期：/ 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

下面是完整的代码，其中ClickProcessButton（self）部分已更新。我确实意识到许多导入对于此脚本都是无用的。

                                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创建所需的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()
