Introduction

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 changes based on some criteria.

The openpyxl module makes it easy to work with Excel spreadsheets. It reads and writes .xlsx files and can be used instead of the deprecated xlrd and xlwt modules. The openpyxl module allows you to look at every cell of a workbook with just a couple of lines of code, including everything from formatting information to hyperlinks!

What is a valueerror?

A valueerror is an error that occurs when a value is not valid. This can happen when a value is not the correct data type, is out of range, or is not in the expected format.

What is openpyxl?

Openpyxl is a Python library for reading and writing Excel 2010 xlsx/xlsm/xltx/xltm files. It was born from lack of existing library to read/write natively from Python the Office Open XML format.

OpenPyXL does not currently support earlier versions of Excel such as Excel 97-2003 (.xls).

How to fix a valueerror?

There are a couple different ways you can fix a valueerror. One way is to try using a different engine, such as “xlsxwriter” instead of “openpyxl”. Another way to fix this error is to make sure that the file you are trying to open exists and that you have the correct path to it.

While light roasts have a higher concentration of caffeine, the perfect roast is a personal choice that is sometimes influenced by national preference or geographic location. There are four color categories of roasts—light, medium, medium-dark, and dark. Within these categories, there are different types of roasts with varying flavors. It’s a good idea to ask before you buy so you know what to expect.
