Convert Excel To Csv With Python Easily

Intro

Learn how to convert Excel to CSV with Python easily and efficiently. Discover the simple steps to export Excel data to CSV format using Python libraries like pandas and openpyxl. Master data conversion, file handling, and scripting with this comprehensive guide, perfect for data analysis and automation tasks.

Converting Excel files to CSV (Comma Separated Values) format is a common task, especially when working with data analysis, machine learning, or data science projects. CSV files are widely supported by most programming languages and tools, making them an ideal choice for data exchange. In this article, we will explore how to convert Excel files to CSV using Python, a popular language for data manipulation and analysis.

Why Convert Excel to CSV?

Excel files (.xls,.xlsx) are proprietary formats developed by Microsoft, which can make it difficult to work with them in certain situations. CSV files, on the other hand, are plain text files that can be easily read and written by most programming languages, including Python. Converting Excel files to CSV can be beneficial in various scenarios:

  • Simplifying data exchange between different applications or systems
  • Enabling data analysis and manipulation using popular libraries like Pandas
  • Improving compatibility with other programming languages or tools

Required Libraries

To convert Excel files to CSV using Python, you will need to install the following libraries:

  • openpyxl: A popular library for reading and writing Excel files (.xlsx,.xlsm,.xltx,.xltm)
  • pandas: A powerful library for data manipulation and analysis
  • csv: A built-in Python library for working with CSV files

You can install these libraries using pip:

pip install openpyxl pandas

Converting Excel to CSV using openpyxl

Here's an example code snippet that demonstrates how to convert an Excel file to CSV using openpyxl:

import openpyxl

# Load the Excel file
wb = openpyxl.load_workbook('example.xlsx')

# Select the first sheet
sheet = wb['Sheet1']

# Create a CSV file
with open('output.csv', 'w', newline='') as csvfile:
    # Iterate over the rows in the sheet
    for row in sheet.rows:
        # Write each row to the CSV file
        csvfile.write(','.join([cell.value for cell in row]) + '\n')

This code loads an Excel file, selects the first sheet, and writes the data to a CSV file.

Converting Excel to CSV using pandas

Alternatively, you can use pandas to convert an Excel file to CSV:

import pandas as pd

# Read the Excel file
df = pd.read_excel('example.xlsx')

# Write the data to a CSV file
df.to_csv('output.csv', index=False)

This code reads an Excel file using pd.read_excel() and writes the data to a CSV file using df.to_csv().

Tips and Variations

Here are some additional tips and variations:

  • Specify the sheet name: When using openpyxl, you can specify the sheet name using the sheet parameter: wb['Sheet2'].
  • Use the engine parameter: When using pandas, you can specify the engine to use for reading and writing CSV files: df.to_csv('output.csv', engine='python').
  • Handle errors: You can handle errors that occur during the conversion process by using try-except blocks.
  • Use other libraries: Other libraries, such as xlrd and xlwt, can also be used to convert Excel files to CSV.
