GPT for Sheets - Autosheet is a Google Workspace add-on that embeds leading AI models inside Google Sheets. Instead of copying data out to a chatbot, you open a side panel, describe what you need in plain language, and the agent reads your spreadsheet, plans the steps and executes them directly in the grid. It handles everyday spreadsheet work — writing, fixing and explaining formulas, cleaning and standardizing messy data, splitting or merging columns, removing duplicates and building pivots and charts.
Its standout strength is bulk processing at scale. You can generate or rewrite content, translate and localize, categorize and classify, extract data from unstructured text, enrich rows with web research, analyze images and run fuzzy matching or deduplication — with the add-on able to reach up to 1,000 requests per minute at peak depending on model latency. The tool supports models from OpenAI (GPT), Anthropic (Claude), Google (Gemini), Perplexity, Parallel and Azure Foundry, and offers bring-your-own-key options so you can use your own API credentials.
Formerly known as GPT for Sheets and Docs, it is now part of the Autosheet product line by parent company Talarian, and GPT for Docs remains available inside the same add-on. It is built for professional and enterprise use with ISO 27001 certification, GDPR compliance, zero data retention, encryption in transit and at rest, and SSO through Google OIDC. Talarian notes it is not affiliated with OpenAI. A Microsoft Excel version, GPT for Excel - Autosheet, is also available.
