SheetGPT was a Google Sheets add-on that put the power of OpenAI's text and image generation directly into spreadsheet cells. Install it, type =GPT("write a product description for...") and get results back instantly. No API keys, no setup, no leaving your sheet.
What it did
- =GPT function — generate text, lists, classifications, and more from any cell
- =GPTLIST function — return multi-row results from a single prompt
- =GPTIMAGE function — generate images inside cells
- No API keys — just install from the marketplace and go
- Multi-user — one plan for an entire Google Workspace org
- Cost-efficient — intelligent caching avoided re-queries
The story
I conceived and built SheetGPT in early 2023, right as OpenAI was opening up API access. It was one of the very first products to bring ChatGPT-style AI into the Google Workspace ecosystem. I grew it to a sustainable user base and eventually sold the business.
The site still lives at sheetgpt.ai and the add-on remains available on the Google Marketplace under new ownership.
