5 Simple Ways to Convert Excel Sheets to CSV Files

Handling and manipulating data in various formats is a common task for many individuals and professionals alike. Microsoft Excel, with its powerful features, remains a popular choice for data analysis and storage. However, there are instances when CSV (Comma-Separated Values) files are preferred due to their simplicity and compatibility with a wide array of applications and systems. This blog post explores five straightforward methods to convert your Excel sheets to CSV files effortlessly.

Why Convert Excel to CSV?

Before diving into the methods, it’s essential to understand why one might need to convert an Excel file to CSV:

• Universality: CSV files are widely supported across different platforms and software, making them an excellent choice for data interchange.
• Simplicity: CSV files are plain text, which simplifies data parsing and manipulation, reducing file size and processing requirements.
• Automation: Many data processing tools and scripts are optimized for CSV due to its straightforward format, enhancing automation processes.

Method 1: Using Excel’s Built-in Feature

Excel provides a native way to convert your workbook to CSV:

1. Open your Excel workbook.
2. Click on File > Save As.
3. Choose a location to save the file.
4. In the Save as type dropdown, select CSV (Comma delimited).
5. Click Save. This process will save your Excel data as a CSV file.

⚠️ Note: Remember that converting Excel to CSV may result in a loss of certain formatting and formulas, as CSV does not support Excel-specific features like macros, cell colors, or charts.

Method 2: Using Online Tools

If you do not have access to Microsoft Excel or prefer an online solution, several websites offer conversion services:

• Zamzar
• Convertio
• Online-Convert

These tools allow you to upload your Excel file, choose the conversion format (CSV in this case), and download the converted file. While convenient, ensure you use a reputable service to safeguard your data privacy.

Method 3: Python Script

Programming enthusiasts might find using Python to convert Excel to CSV particularly appealing:

import pandas as pd



df = pd.read_excel(‘input.xlsx’)



df.to_csv(‘output.csv’, index=False)

This script uses the pandas library to read an Excel file and then save it as a CSV file. Make sure to install pandas using pip install pandas.

Method 4: Power Automate in Microsoft 365

Microsoft Power Automate can automate repetitive tasks, including converting Excel files to CSV:

1. Log into Power Automate.
2. Create a new flow.
3. Add a step to upload your Excel file or fetch it from a specific location.
4. Add the ‘Convert Excel to CSV’ action.
5. Configure the action to select your input file and specify where to save the CSV output.
6. Run the flow or set it up to trigger automatically when certain conditions are met.

🔎 Note: Power Automate can be incredibly powerful for batch conversions or scheduled tasks, ensuring regular backups or data processing workflows.

Method 5: Command Line Tools

For those comfortable with command-line interfaces, tools like in2csv or xlsx2csv can be used:

• in2csv -f xlsx input.xlsx > output.csv
• xlsx2csv input.xlsx output.csv

These tools are available on many Unix-like systems and can be installed via package managers like Homebrew on macOS or apt on Ubuntu.

Converting Excel files to CSV is an essential skill for anyone dealing with data. From simple file conversion for compatibility to leveraging automation for batch processes, the methods outlined here offer flexibility to meet various needs. Understanding the strengths and limitations of each approach enables you to choose the best method for your specific situation, enhancing efficiency in data handling.
