How can I export all data to an Excel file using openpyxl?

Question

I am trying to write all the data inputted by my user to an Excel file, with each new entry being entered underneath the most recent one.

It should do this in my GUI once I click submit.

I managed to get the headings to show.

I am using the openpyxl library, I googled and this was the first to come up.

My GUI for reference:

Here is the section of my code:

filepath = "C:\xxxx\xxxx\xxxx\xxxx\xxxx\Collecting Data.xlsx"
            
if not os.path.exists(filepath):
    xlsx_open = openpyxl.Xlsx_openxlsx_open()
    sheet = xlsx_open.active
    table_headings = ["Card Type", "Staff Number", "Staff Name", "Staff Title", "Department", "Safety Function", "Safety Standards", "Brief Description of the Incident"]
    sheet.append(table_headings)
    xlsx_open.save(filepath)
    xlsx_open = openpyxl.load_xlsx_open(filepath)
    sheet = xlsx_open.active
    sheet.append([staff_name_entry, staff_id_dropdown, staff_title_entry, department_entry, 
                  card_type_dropdown, safety_function_dropdown, safety_standard_dropdown, manualy_text_entry])
    xlsx_open.save(filepath)

window.mainloop()

This is the error I get.

Error: submit_form sheet.append([CardTypeDropdown, StaffIdDropdown, StaffNameEntry, StaffTitleEntry, DepartmentEntry, ^^^^^^^^^^^^ AttributeError: ‘NoneType’ object has no attribute ‘append’

Answer 1

Alright so I ended up figuring it out myself through the following changes:

I made a new variable called "entries" containing a list of the inputs so that the append function would recognize it as a function.
I changed the double ” to a single ‘/’ in the ‘filepath’ variable to resolve the ‘NoneType’ error.

I’m not sure if a combination of these 2 solutions fixed it or it was a single solution that fixed it, but nonetheless it’s done the job. I’ll leave it to the people who are more experienced with python to answer that 🙂

P.S: I’m pretty sure the code can look a lot better and simpler, but again, I’m a python newbee… at least it works 😀
