Google Sheets is where a huge amount of real work happens — tracking inventory, managing leads, analyzing feedback, preparing reports. But much of that work is repetitive: writing formulas, cleaning messy data, translating columns, categorizing rows one by one.
What if you could describe what you need in plain language and have AI do it directly in your spreadsheet?
That's exactly what GPT for Sheets does. It's a Google Sheets add-on that integrates an AI agent directly into the Sheets interface. You type what you need, and the AI reads your data, figures out the steps, and executes them — right where you work.
Why use AI in Google Sheets?
AI in Google Sheets isn't about replacing what you know how to do — it's about removing the parts that slow you down.
With GPT for Sheets, you can automate everyday spreadsheet tasks like writing and fixing formulas, formatting cells, cleaning up inconsistent data, and creating charts and pivot tables. You can also process large datasets row by row — translating, categorizing, enriching, scoring, or generating content — with a unique result for each row.
All from a single plain-language instruction, without leaving your spreadsheet. No copy-pasting between Sheets and AI chatbots. No formula writing. No complex prompt engineering.
And you're not locked into a single AI provider. GPT for Sheets gives you access to models from Anthropic, OpenAI, and others — including Claude Opus 4.6 and GPT-5.4 — so you can pick the best model for each task.
How to install GPT for Sheets
Getting started takes about a minute.
- Go to the GPT for Sheets and Docs installation page on the Google Workspace Marketplace.
- Click Install and confirm any permissions.
Once installed, GPT for Sheets is available from any spreadsheet. To open it, go to Extensions > GPT for Sheets and Docs > Open. The add-on sidebar appears on the right side of your spreadsheet.
No API key is required to get started, and the add-on comes with a free trial. Check out the available models.
Getting started with the Agent
The Agent is the chat interface for spreadsheet work in GPT for Sheets. It's the easiest and most powerful way to use AI in your spreadsheet. Simply describe what you need in plain language — from everyday spreadsheet tasks to row-by-row bulk processing across large datasets — and let the AI take it from there.
Here's how it works:
- Open your spreadsheet.
- Open GPT for Sheets from the Extensions menu.
- In the sidebar, select Agent.
- Type what you need. For example:
Fill out this tableorTranslate column B to FrenchorFix the formula in H2. - Click the send button.
The Agent analyzes your request, drafts a plan, and executes it. You can follow its thinking and progress live in the sidebar.
Try it with a built-in example
The fastest way to see the Agent in action is to use one of the built-in examples:
- In the sidebar, in the Agent tab, click Examples and select Market research.
- GPT for Sheets creates a new sheet with sample data — a list of company names and empty columns for company information.
- The Agent chat field is prefilled with a prompt:
Fill out this table. - Click the send button. The Agent searches the web for each company and fills in the missing information, column by column.
That's it. One prompt, and the Agent handles the research, the web lookups, and the data entry.
What you can do with GPT for Sheets
GPT for Sheets is suitable for both everyday spreadsheet tasks and high-volume workflows involving large datasets. Here are some of the most common things people use it for.
Everyday spreadsheet tasks
Write formulas. Describe what you want to calculate in plain language, and the Agent generates the right formula, inserts it, and fills it across your range. No need to memorize syntax.
Find and fix errors. Ask the Agent to check a formula or spot inconsistencies in your data. For example: Fix the formula in H2 or Highlight rows where the email format is invalid.
Format and standardize. Clean up messy data — inconsistent date formats, mixed capitalization, trailing whitespace — or apply formatting across entire sheets.
Create charts and pivot tables. Describe the visualization you need, and the Agent builds it from your data.
Row-by-row bulk processing
Translate at scale. Translate product descriptions, customer tickets, or any column into one or more target languages — with support for glossaries and localization conventions.
Generate content. Write SEO-optimized product descriptions, ad copy, or summaries from your existing data. Just provide a single prompt and get a unique result for every row.
Enrich your data. The Agent can search the web to fill in missing information — company details, contact data, market intelligence — and write it directly into your sheet.
Categorize and score. Classify support tickets, tag survey responses, or score and qualify sales leads based on criteria you define.
Beyond the Agent: Bulk tools and GPT functions
The Agent is the primary interface for spreadsheet work in GPT for Sheets, but it's not the only one. GPT for Sheets also provides two additional features for users who need more control or a different workflow.
Bulk tools
Bulk tools let you process a column row by row with precise manual control over the prompt, model, and settings. They're useful when you want to fine-tune exactly how the AI processes your data, or when you want to save and reuse specific prompt configurations.
You configure and run bulk tools from the sidebar — no formulas needed. GPT for Sheets includes dedicated bulk tools for common operations like translation, classification, and extraction, as well as a custom prompt tool for anything else.
GPT functions
GPT functions are custom spreadsheet functions that let you use AI directly inside formulas. They work like native Sheets functions: you can drag them across rows and columns, nest them with other functions, and get results that update automatically when inputs change.
GPT functions are best suited for advanced users who are comfortable writing formulas and want reactive, formula-driven AI workflows.

Which should you use?
Agent | Bulk tools | GPT functions |
|---|---|---|
Easy | Moderate | Advanced |
Chat in plain language to automate everyday spreadsheet tasks or process large datasets row by row. No prompt engineering required. | Fill a column by processing rows one by one, with precise manual control over the prompt, model, and settings. | Use custom functions in formulas to process rows and columns, or get reactive behavior that reruns automatically when input changes. |
As a rule, start with the Agent. It handles the vast majority of use cases and requires no setup or configuration.
