Word Cloud Creator

Romain Vialard, Oct 2012

This library provides one single method to create an HTML Word Cloud from a text input.


A word cloud is a visual representation for text data, typically used to depict keyword metadata (tags) on websites, or to visualize free form text. Tags are usually single words, and the importance of each tag is shown with font size or color. This format is useful for quickly perceiving the most prominent terms and for locating a term alphabetically to determine its relative prominence.






You can also use this library outside of Apps Script: This Word Cloud Creator is available as a REST API and a Web Application.
REST API: send an HTTP post request to the url above, with the text you want and you will get the HTML code of the corresponding word cloud in return.
