Once upon a time there was a Google Spreadsheets script that would create word clouds for you. When the new (current) version of Google Spreadsheets was launched that script stopped working. This morning I found a replacement for that old script.
When you have a Google Document open, open the Add-ons menu and search for “tag cloud generator.” The Tag Cloud Generator Add-on will create a word cloud in the right-hand margin of any of your Google Documents that contain more than one hundred words.
Applications for Education
Word clouds can help students analyze documents written by others as well as documents of their own creation. By copying the text of a document into a word cloud generator your students can quickly see the words that appear most frequently in that document. Word clouds can also be used to help students see which words that they have frequently used in their own works. Have your students create word clouds of their work during the revision process of writing a story or essay. The word cloud will quickly show students which words they have used the most. Then ask them to think about synonyms for the words that they have used most often in their writings.
