Sorting a CSV file by a given column can be a useful task when working with large datasets. Excel and Python both offer simple solutions for sorting CSV files. In this article, we will explore how to sort a CSV file by a given column using both Excel and Python.

Sorting a CSV file using Excel

Excel provides an easy-to-use interface for sorting data in CSV files. To sort a CSV file in Excel, follow these steps:

  • Open the CSV file in Excel.
  • Click on the column header of the column you want to sort by. This will select the entire column.
  • Click on the "Data" tab in the ribbon at the top of the screen.
  • Click on the "Sort A to Z" or "Sort Z to A" button, depending on whether you want to sort the column in ascending or descending order.
  • Excel will ask you if you want to expand the selection to include adjacent columns. If the CSV file only contains one column of data, you can click "Sort" to proceed. Otherwise, select the option that is appropriate for your data.
  • Excel will sort the data in the selected column.
  • Save the sorted CSV file.

Sorting a CSV file using Python

Python provides a powerful library called Pandas for working with data in CSV files. To sort a CSV file in Python, follow these steps:

  • Import the Pandas library.

import pandas as pd

2. Load the CSV file into a Pandas DataFrame.


df = pd.read_csv('filename.csv')
  • Sort the DataFrame by the column of your choice.

sorted_df = df.sort_values(by='column_name')
  • Save the sorted DataFrame to a CSV file.

sorted_df.to_csv('sorted_filename.csv', index=False)

In the above code, 'filename.csv' is the name of the original CSV file, 'column_name' is the name of the column you want to sort by, and 'sorted_filename.csv' is the name of the sorted CSV file.

Conclusion:

Sorting a CSV file by a given column is a straightforward task that can be accomplished using Excel or Python. Excel provides an easy-to-use interface for sorting data, while Python provides a powerful library for working with data in CSV files. Whether you prefer a graphical interface or writing code, you can easily sort a CSV file by a given column using these tools.
