How to loop through rows of the Excel sheet using openpyxl?

I am using Python, Selenium, openpyxl in order to fill a form online. To fill the form I am taking values from specific cells on excel (.xlsx). (to test the code you can just create and excel file with 2 columns, insert under column A some names and column B some age.

From the cell A2, I take the NAME of the person and insert it into the online form
From the cell B2, I take the LASTNAME of the person and insert it into the online form
Then I click 'Reset' (This is an example but in the real code I will click save as a draft).

I would like to create a loop in which the code will start again from driver.get("https://www.roboform.com/filling-test-all-fields") to go again to the page where I need to fill out the form, but this time I would like to take:

From the cell A3, the NAME of the person and insert it into the online form
From the cell B3, the LASTNAME of the person and insert it into the online form
And click 'Send as a draft' again

Then again, another loop to insert the data from row 4, so I would like to program to read again my code from driver.get("https://www.roboform.com/filling-test-all-fields") but this time take values from A4 and B4, and so on, until the row on excel is empty.

With the following code I can insert the data to the online form:

from selenium import webdriver
from selenium.webdriver.chrome.webdriver import WebDriver
from selenium.common.exceptions import NoSuchElementException
import openpyxl

driver: WebDriver = 
webdriver.Chrome("/Users/HHHHH/PycharmProjects/excel/driver/chromedriver")

driver.maximize_window()

excel_document = openpyxl.load_workbook(r"/Users/XPATH OF THE EXCEL FILE YOU CREATE TO TEST THIS CODE", 
data_only=True)

sheet = excel_document["Sheet1"]



driver.get("https://www.roboform.com/filling-test-all-fields")

#Insert in the form the Name of the person

prevsymbol = sheet["A2"].value
if prevsymbol == None:
    pass
else:
    try:
        driver.find_element_by_name("02frstname").send_keys(sheet["A2"].value)
    except NoSuchElementException:
        print("A2:(name) Not Found")

#Insert in the form the Last Name of the person

prevsymbol = sheet["B2"].value
if prevsymbol == None:
    pass
else:
    try:
        driver.find_element_by_name("04lastname").send_keys(sheet["B2"].value)
    except NoSuchElementException:
        print("B2:(Lastname) Not Found")

#click Save as a draft

driver.find_element_by_xpath("//*[@value='Reset']").click()
