    How To Read excel file Using openpyxl

    The openpyxl package has load_workbook() method that will use to open xlsx file. There is a number of helper methods that help to read and write excel file.

    path
    = "C:\\employee.xlsx" wb_obj = openpyxl.load_workbook(path.strip()) # from the active attribute sheet_obj = wb_obj.active

    We have also set the active sheet to read the data of the excel file.

Cách nhận và đặt dữ liệu tệp Excel

Chúng tôi sẽ nhận được đối tượng ô Row và sau đó nhận giá trị ô bằng thuộc tính .value.

//get col object 
salary_cell=sheet_obj.cell(row=i,column=2) 
//get value 
salary = salary_cell.value: 
//set value 
salary_cell.value = 2000;

Tôi đã hợp nhất tất cả các phần của mã và thêm chúng vào tệp emp.py.

import sys
from colorama import Fore, init, Back, Style
import openpyxl
import re

init(convert=True)
print("\n")
path = input("Enter xls file path, ex- C:\\employee.xlsx : ")
input_col_name = input("Enter colname, ex- Endpoint : ")
try:
    print(Fore.RESET)
    #path = "C:\\employee.xlsx"
    wb_obj = openpyxl.load_workbook(path.strip())
    # from the active attribute 
    sheet_obj = wb_obj.active

    # get max column count
    max_column=sheet_obj.max_column
    max_row=sheet_obj.max_row
    for j in range(2, 5):
        salary_cell=sheet_obj.cell(row=i,column=2)
        if salary_cell.value > 1500:
            salary_cell.value =  salary_cell.value+500

    wb_obj.save()
except Exception as e:
    print(e)
    print (Fore.RED + "Error : The file does not found")
print(Fore.GREEN + "###################### Successfully! Excel file has been read/write. ##############################")
