Getting Started questions

Setting up SheetMagic takes about 3 minutes. Install the extension from the Google Workspace Marketplace, then add your API key via Extensions → SheetMagic → Set API keys. Step-by-step guides are available in the dashboard after you sign in.

SheetMagic supports all major AI models including GPT-5.5, GPT-4o, Claude Opus 5, Claude Sonnet 5, Gemini 3.1 Pro, Llama 4, and many more. For image generation, dedicated models like GPT Image 2, DALL-E 3, Gemini 3 Pro Image, and Gemini 3.1 Flash Image are available. You can access different models depending on your API provider: OpenAI, Anthropic, Google, Mistral, OpenRouter, or Perplexity.

No! All paid plans include platform-managed API keys. You can start using AI features immediately. If you prefer, you can enable BYOK (Bring Your Own Key) to use your own API keys from OpenAI, Anthropic, Google, Mistral, OpenRouter, or Perplexity for unlimited usage at provider rates.

Yes, SheetMagic requires you to bring your own API keys from providers like OpenAI, Anthropic, or Google. Consumer subscriptions (ChatGPT Plus, Claude Pro) are separate products for their chat interfaces and don't include API access. You'll need to create API keys at each provider's developer platform, where usage is billed based on your actual usage.

No, SheetMagic only works in Google Sheets on desktop web browsers. The Google Sheets mobile app does not support add-ons or custom functions. For the best experience, use Chrome, Firefox, Safari, or Edge on a computer.

No, SheetMagic is built exclusively for Google Sheets using Google Apps Script. It does not work with Microsoft Excel. If you need Excel support, you would need to use a different tool.

Each person who wants to use SheetMagic functions needs their own SheetMagic subscription and API key. When you share a sheet, collaborators will see the results of your formulas, but they cannot run SheetMagic functions themselves without their own subscription.

API costs vary by model and usage. As a rough guide: GPT-4o-mini costs about $0.15 per million input tokens (~750,000 words). For typical use cases like generating product descriptions, expect to spend $1-5/month for light usage, $10-30/month for moderate usage. Check your provider's pricing page for exact rates.

OpenAI is best for beginners, simple setup, reliable, and includes GPT-4o with web search. Anthropic gives you Claude models with web search support. Google offers Gemini models with strong performance and native image generation via Gemini 3 Pro/Flash Image. OpenRouter gives you access to 200+ models from multiple providers with one API key. Perplexity is great for research tasks with built-in web search. Most users start with OpenAI or Anthropic.
