Sheet Ninja

Sheet Ninja is a tool that connects to your Google Sheets and automatically generates a live, functional API endpoint. You simply structure your data in a spreadsheet with headers in the first row and your data below, paste the sheet's link into Sheet Ninja, and it gives you a URL to access that data programmatically. It handles all the backend complexity, so you can focus on building the frontend of your application.

The tool works by using Google's OAuth for secure access to your sheet. It reads your column headers to define the API's data structure, and any changes you make in the sheet are instantly reflected through the API. It provides copy-paste prompts for popular AI coding tools like Claude, Replit, and ChatGPT, making it easy to integrate your new API into a project without deep technical knowledge.

Sheet Ninja is ideal for developers, founders, and marketers who need to prototype apps quickly or manage simple data-driven projects without setting up a traditional database. Use cases include building waitlist forms, internal tools, live menus for restaurants, simple dashboards, or even providing a data source for AI agents. It lets you test ideas in hours instead of days.
