from openpyxl import load_workbook

wb = load_workbook(filename=r'C:\Users\Hp\Desktop\Test data.xlsx' )

ws = wb['Sheet1']

range=ws['B2':'B10']

for cell in range:

    for x in cell:

        y=x.value

        print(y)

win=Tk()

clicked=StringVar()

combodata=ttk.Combobox(win, width=100,state='readonly')

combodata['values']=[(y)]

combodata.pack(pady=20)

win.mainloop()

I have prepared this code. This prints all values in the column but when it comes to tkinter-dropdown, it just provides the option of last value in the range provided i.e. B10 only. Can any of you please modify this code according to my need? I have more than 1000 values in the column. Thanks in advance.

Make an empty list, then append each value in the column. Also, be sure you don't use reserved keywords as variables.

Code:

from openpyxl import load_workbook
from tkinter import *
import tkinter.ttk as ttk

# Load the xlsx file, then store the value of each column in the "elements" list
wb = load_workbook(filename=r"C:\Users\Hp\Desktop\Test data.xlsx")
ws = wb['Sheet1']
xlsx_range = ws['B2':'B10']
elements = []

for cell in xlsx_range:
    for x in cell:
        y = x.value
        elements.append(y)
        print(y)


# Tkinter stuff
win = Tk()
clicked = StringVar()

combodata = ttk.Combobox(win, width=100,state='readonly', values=elements)
combodata.pack(pady=20)

win.mainloop()
