使用Python合并Excel文件中的多个Sheet的实现过程

        self.button = wx.Button(panel, label="Select Excel File")
        self.button.Bind(wx.EVT_BUTTON, self.on_open_file)

        vbox.Add(self.button, 0, wx.ALL | wx.CENTER, 5)
        panel.SetSizer(vbox)

    def on_open_file(self, event):

            if fileDialog.ShowModal() == wx.ID_CANCEL:
                return

            path = fileDialog.GetPath()
            self.merge_sheets(path)

    def merge_sheets(self, filepath):
        wb = load_workbook(filepath)
        new_wb = Workbook()
        new_ws = new_wb.active
        new_ws.title = "Merged Sheet"

        for i, sheet_name in enumerate(wb.sheetnames[:5]):
            ws = wb[sheet_name]
            for row in ws.iter_rows(values_only=True):
                new_ws.append(row)

        save_path = filepath.replace('.xlsx', '_merged.xlsx')
        new_wb.save(save_path)
        wx.MessageBox(f"Merged file saved as: {save_path}", "Info", wx.OK | wx.ICON_INFORMATION)
