Application scenario

This code can be used to modify the metadata of Excel files, such as author, subject, description, etc. By using Python and Openpyxl modules, and the wxPython library, we can create a GUI interface to Enter metadata and save this metadata with the Excel file.

Here are a few possible application scenarios:

Use metadata to more quickly identify and find large numbers of Excel files, especially if they need to be categorized and managed.

Data Sharing: When you need to share an Excel file with others, metadata can provide useful information such as author, subject, and description.

Using metadata allows you to more easily identify and differentiate between multiple Excel files, speeding up the data analysis process.

Data Reporting: When you need to reference an Excel file in a report, metadata can provide useful information such as author, subject, and description.

In short, this code can be used in any scenario where the metadata of an Excel file needs to be modified, from data management to data analysis to data reporting, everything can be achieved through this code.

The effect is as follows

Source code description

With the help of the GUI interface built by the wxPython module, users can enter the attributes of the Excel file that need to be modified. Users can enter the author, creation time, modification time, title, subject and description, and then click the "Save" button to save these properties and write them into the corresponding properties of the Excel file.

This code creates a wxPython window named PropertyEditor, which contains text boxes for entering Excel file properties and a "Save" button. When the "Save" button is clicked, it will get the Excel file that the user wants to modify and save the entered property values into the properties of the Excel file. It then displays a message box prompting the user that the save was successful.

Please note that this program assumes that the user already knows the path to the modified Excel file. Using the wxPython module's file dialog box, users can browse the file system to select Excel files.
