Simple steps to use: 1. Select a column of cells with text you want to analyze. 2. Click the analyze button in the sidebar. 3. Sentiment scores are output on a new sheet. The analysis is performed by code running in the sidebar in your browser, instead of sending it to a cloud API for processing. This means the add-on can provide you with unlimited processing at no cost. Also, your text data never leaves the Google Sheets™️ environment.
