How to Write a Pandas DataFrame to a CSV file

by ganesh Updated: Jan 17, 2023

A DataFrame is a tabular data structure with rows and columns that can carry any form of data and is two-dimensional size mutable. It is a crucial component of the "pandas" library, a well-liked Python library for data manipulation and analysis. A dataframe's rows and columns may be used to access and edit the data. Additionally, you may execute operations on the data using a variety of functions and methods from the pandas' library, including filtering, aggregation, and transformation.


In Python, DataFrames are a crucial tool for manipulating and analyzing data. 

  • pandas: It is designed to operate effectively with huge datasets. In the field of data science, it is frequently used for operations including data preparation, cleansing, and analysis. 

You can use the to_csv() method of a pandas DataFrame to write the contents of the DataFrame to a CSV (comma-separated values) file. 

  • to_csv(): This is used to write the DataFrame to a specific location on your filesystem by specifying the full path to the file as the first argument. 

The to_csv() function offers a wide range of additional arguments that you may use to alter the output. For instance, you may use the "header" argument to include or remove the column names in the output or the "sep" parameter to define a different delimiter for the columns. 


Here's an example of how to write a Pandas DataFrame to a CSV file.

Code


In this solution, we use the to_csv function of the Pandas library

  1. Copy the code using the "Copy" button above, and paste it in a cell of Jupyter notebook.
  2. Modify the path the file to be written.
  3. Run the cell to write a Pandas dataframe to a csv.
  4. Install the 'openpyxl' library using the command "pip install openpyxl" and run the cell to write a Pandas dataframe to excel.


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for "write dataframe to excel" in kandi. You can try any such use case!

If you do not have Pandas that is required to run this code, you can install it by clicking on the above link and following the installation instruction from either Github or Pypi links through the Pandas page in kandi.


You can search for any dependent library on kandi like Pandas.

Environment Tested


I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in Python3.7.
  2. The solution is tested on Pandas 1.3.1 version.


Using this solution, we are able to read online data and create a Dataframe using the Pandas library in Python with simple steps. This process also facilities an easy to use, hassle free method to create a hands-on working version of code which would help us read data in Pandas.
