Create a word cloud from csv in Python

by ganesh Updated: Nov 28, 2022

As developers we encounter many situations where we need to work with text data in our applications for . Python has many libraries which provide the ability to work with text data and visualize them in forms of images. WordCloud and Matplotlib are comprehensive and popular Python libraries. In this solution kit, I am sharing the code snippet and library that I use to create a WordCloud of words from csv using WordCloud and Matplotlib in Python which can be executed directly in the IDE.

Code

In this solution we use the generate function of the WordCloud library.

Creating word cloud in Python from column in CSV file

import csv
from wordcloud import WordCloud


#read first column of csv file to string of words seperated
#by tab

your_list = []
with open('words.csv', 'rb') as f:
    reader = csv.reader(f)
    your_list = '\t'.join([i[0] for i in reader])


# Generate a word cloud image
wordcloud = WordCloud().generate(your_list)

# Display the generated image:
# the matplotlib way:
import matplotlib.pyplot as plt
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis("off")

# lower max_font_size
wordcloud = WordCloud(max_font_size=40).generate(your_list)
plt.figure()
plt.imshow(wordcloud, interpolation="bilinear")
plt.axis("off")
plt.show()

# The pil way (if you don't have matplotlib)
# image = wordcloud.to_image()
# image.show()

Copy the code using the "Copy" button above, and paste it in a Python file in your IDE.
Create a csv file with one column containing words.
Modify the reading mode in the code from 'rb' to 'r'
Modify the name, location of the csv to be read in the code.
Run the file to create a WordCloud.

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 "create word cloud from csv" in kandi. You can try any such use case!

If you do not have Matplotlib and WordCloud that are required to run this code, you can install them by clicking on the above link and copying the pip Install command from the Matplotlib and WordCloud pages in kandi.

You can search for any dependent library on kandi like Matplotlib and WordCloud.

Environment Tested

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

The solution is created in Python3.9.
The solution is tested on Matplotlib 3.4.3 and WordCloud 1.8.1 version.

Using this solution, we are able to create a Wordcloud from csv using the WordCloud and Matplotlib libraries 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 create a word cloud from csv in Python.
