SheetAI Review: AI Inside Google Sheets for Faster Data Work

1. Introduction – Why SheetAI Stands Out

SheetAI stands out as a lightweight yet powerful AI layer for Google Sheets, letting users run prompts, generate content, clean data, and even create images directly inside the spreadsheet grid. Instead of forcing teams onto a new platform, it augments an existing, familiar environment, which is attractive for tech professionals who already live in Sheets. With a reported ~139k installs and a 4.5/5 rating, SheetAI has gained traction as one of the more mature AI add-ons for Google Workspace.

2. What Is SheetAI? – Background, Purpose, Technology

SheetAI is a Google Sheets add-on that embeds ChatGPT-style capabilities and multi-model AI directly into spreadsheets via custom functions and a sidebar interface. Its core purpose is to automate repetitive spreadsheet tasks (formulas, data cleaning, enrichment, content generation) and enable natural-language interaction with data, without scripts or external tools.

Technically, SheetAI connects to large language models via APIs (OpenAI, Claude, Gemini, xAI, OpenRouter, and more), exposing them as spreadsheet formulas like =SHEETAI(), =SHEETAI_LIST(), and =SHEETAI_TABLE(). Users can either use their own API keys (recommended for cost control) or rely on SheetAI’s managed setup, depending on plan.

3. Key Features – 4–6 Main Functions

3.1 Ask AI Anything in Sheets

SheetAI’s flagship function =SHEETAI() lets users type a natural-language prompt in a cell and receive an AI-generated response, similar to ChatGPT but contextually integrated with the sheet. Typical uses include generating text, explanations, formulas, or short analyses tied to row data.

3.2 AI with Memory & Custom “Brain”

The SHEETAI_BRAIN concept allows users to “train” AI on their own data via text or URLs, enabling more contextual and accurate responses based on company-specific information. This helps turn generic models into tailored assistants for recurring internal use cases such as support responses, product data, or documentation.

3.3 Structured Content and List/Table Generation

Functions like SHEETAI_LIST and SHEETAI_TABLE generate structured lists and tables on command, useful for creating datasets, ideas, product variations, or scenario matrices at scale. This pushes SheetAI beyond pure text generation into practical data production and rapid prototyping directly in the grid.

3.4 Smart Auto-Fill and Data Enhancement

SheetAI includes “magic fill” concepts for smart auto-fill and enrichment, such as standardizing data, extracting entities, classifying items, or enriching rows with descriptions. The SHEETAI_EXTRACT function is used for extraction and transformation—e.g., isolating company names, cleaning addresses, or categorizing reviews into sentiment buckets.

3.5 Formula Generation and Prompt Variations

The add-on can generate spreadsheet formulas from natural language (via a sidebar “formula generator”), helping users who struggle with complex expressions like nested IF, REGEX, or ARRAYFORMULA constructs. It also supports running multiple prompt variations over ranges via functions like =SHEETAI_RANGE, enabling batch operations on entire columns.

3.6 Multi-Model and Media Support

Beyond text, SheetAI integrates with APIs like Replicate for video, OCR, images, and audio, depending on configuration. Combined with multi-model support (GPT-4, Claude, Gemini, xAI, OpenRouter), it offers flexibility in cost, latency, and quality trade-offs for different tasks.

4. User Experience – Ease of Use, UI, Integrations

Installation is handled via the Google Workspace Marketplace; once installed, users launch it from Extensions → SheetAI App → Launch. The UI consists of:

  • A sidebar for configuring tasks, generating formulas, and managing prompts.
  • In-cell functions (=SHEETAI, etc.) for direct use in formulas.

Reviews describe setup as quick, with no extra software beyond the add-on and an API key if desired. Because it runs entirely inside Google Sheets, it fits into existing workflows and benefits from Sheets’ built-in sharing, collaboration, and access control.

Integrations are primarily model-side (OpenAI, Anthropic, Google Gemini, etc.) and via generic APIs (e.g., Replicate), rather than app-specific connectors like CRM integrations. That makes SheetAI more of a horizontal automation layer than a domain-specific analytics platform.

5. Performance and Results – Real Use Cases

Independent reviews and deep dives report substantial productivity gains:

  • Users automate “hours of manual work” by using SheetAI for pattern analysis, categorization, and data cleanup.
  • Typical tasks include generating lists, summarizing feedback, cleaning email lists, creating product descriptions, and writing personalized messages in bulk.
  • With multi-model support, users can choose cheaper or faster models for high-volume tasks while reserving premium models like GPT-4 for more complex reasoning or content.

SheetAI carries the usual caveats of LLM tools: occasional inaccuracies or outputs that require refinement, and costs tied to token usage when using external API keys, especially with heavy workloads. Still, ratings around 4.5/5 and a growing install base suggest strong perceived value among active users.

6. Pricing and Plans – Free vs Paid

Public information from SERP AI, TenereTeam, and other aggregators shows a simple three-tier model:

  • Free – $0/month
    • 5 Sheet formula generations per month.
    • 50 SHEETAI function calls per month.
    • Access to past formulas and function calls.
    • Caching to reduce repeated API costs.
    • Works in all languages.
  • Unlimited Monthly – $8/month
    • Unlimited formula generations.
    • Unlimited SHEETAI function calls.
    • Requires own OpenAI (or other) API key.
    • All Free features included.
  • Unlimited Yearly – $72/year
    • Same as Unlimited Monthly, with discounted annual billing.

This pricing model keeps the SheetAI subscription low while actual compute costs are governed by your model provider (e.g., OpenAI), which charges per token. For individuals or small teams already using OpenAI, the combined cost is competitive versus standalone SaaS AI tools.

7. Pros and Cons – Balanced Summary
