Working with Excel Spread sheets in python

 

Introduction 

Excel is a popular and powerful spread- sheet application for Windows. Python Course in Bangalore the openpyxl module allows your Python programs to read and modify Excel spreadsheet files. For example, you might have the boring task of copying certain data from one spreadsheet and pasting it into another one. Or you might have to go through thousands of rows and pick out just a handful of them to make small edits based on some criteria. Or you might have to look through hundreds of spreadsheets of department budgets, searching for any that are in the red. These are exactly the sort of boring, mindless spreadsheet tasks that Python can do for you.

Excel Documents

First, let’s go over some basic definitions: An Excel spreadsheet document is called a workbook. A single workbook is saved in a file with the .xlsx exten-sion. Each workbook can contain multiple sheets (also called worksheets). The sheet the user is currently viewing (or last viewed before closing Excel) is

called the active sheet.

Each sheet has columns (addressed by letters starting at A) and rows

(addressed by numbers starting at 1). A box at a particular column and row is

called a cell. Each cell can contain a number or text value. The grid of cells

with data makes up a sheet.

Installing the openpyxl Module

Python does not come with OpenPyXL, so you’ll have to install it. Python with Python Training in Bangalore Follow the instructions for installing third-party modules in Appendix A; the name of the module is openpyxl. To test whether it is installed correctly, enter the following into the interactive shell.  Here’s a step-by-step guide on how to install the openpyxl module, which is a popular Python library used for reading and writing Excel files.

Step-by-Step Guide to Install openpyxl

1. Check Python Installation

Before installing openpyxl, make sure you have Python installed on your system. You can check this by running:

2. Install pip

Pip is the package installer for Python. It usually comes pre-installed with Python, but you can check if it's installed by running:

3. Install openpyxl

You can install the openpyxl module using pip. Open your command prompt (Windows) or terminal (MacOS/Linux) and run:

Verify Installation

To verify that openpyxl is installed correctly, you can run the following in a Python interactive shell

Ideas for Similar Programs

Many businesses and offices use Excel to store various types of data, and it’s not uncommon for spreadsheets to become large and unwieldy.Python Training Certification in Bangalore Any program that parses an Excel spreadsheet has a similar structure: It loads the spreadsheet file, preps some variables or data structures, and then loops through each of the rows in the spreadsheet. Such a program could do the following:

• Compare data across multiple rows in a spreadsheet.

• Open multiple Excel files and compare data between spreadsheets.

• Check whether a spreadsheet has blank rows or invalid data in any cells and alert the user if it does.

• Read data from a spreadsheet and use it as the input for your Python programs.

Writing Excel Documents

OpenPyXL also provides ways of writing data, meaning that your programs can create and edit spreadsheet files. With Python, it’s simple to create spreadsheets with thousands of rows of data.
