GPT for Work (including GPT for Sheets and Docs) is an AI agent that runs inside Google Sheets, Google Docs, and Microsoft Excel. Instead of copying data into a separate chatbot, you run prompts on cells, ranges, and documents to clean data, write formulas, classify rows, translate, generate marketing copy, summarize notes, and bulk-process tables.
Typical workflows include normalizing messy lists, extracting entities, tagging products, drafting titles and descriptions, building spreadsheet formulas, and analyzing columns at scale. It can connect to multiple large language models (depending on plan and configuration), so teams pick speed vs. quality tradeoffs for each job.
Install from the Google Workspace Marketplace or Microsoft add-in flows, start with free usage where available, then pay for higher volume. Always review AI output in spreadsheets before using it in production finance or compliance work.
