I am completely new to openpyxl so, as you can imagine, I am having pretyy hard times when I try to make use of it.
I have an excel report that contains only one sheet
There's no need to use the pandas for this.
from openpyxl import Workbook
import openpyxl
file = "enter_path_to_file_here"
wb = openpyxl.load_workbook(file, read_only=True)
ws = wb.active
for row in ws.iter_rows("E"):
for cell in row:
if cell.value == "ABC":
print(ws.cell(row=cell.row, column=2).value) #change column number for any cell value you want
