Description

Who is this for

This template is designed for e-commerce businesses, customer support teams, and marketing professionals who need to monitor and analyze customer reviews at scale. It's especially useful for teams dealing with multilingual reviews (Japanese to English) and those who want instant alerts for critical feedback.

What it does

This workflow automatically processes customer reviews stored in Google Sheets using OpenAI GPT. For each review, it performs:

Translation** from Japanese to English
Sentiment analysis** with a score from -1.0 to +1.0
Importance classification** (High/Medium/Low) based on urgency
Category tagging** (Quality, Price, Shipping, Support, Features, Usability, Other)
Key phrase extraction** for quick summary

Results are written back to the spreadsheet, and Telegram notifications are sent based on priority level.
