Sentiment Analysis in Excel: Using AI on Customer Reviews
o11 Team
Excel is great for numbers, but terrible for text. until now. With o11, you can perform NLP (Natural Language Processing) directly in the grid.
The Use Case
You have a column of feedback: “Product great, but shipping slow.” Ask o11:
“Add a column for ‘Sentiment’ (Positive/Negative) and a column for ‘Category’ (Product/Service).”
o11 reads each row and tags it. Now you can pivot the data: “Show me the count of Negative reviews by Category.” Insight unlocked.
