# Introduction

Welcome to the Sheet Ninja documentation 👋

Use Sheet Ninja to power internal tools, sync data between systems, or prototype production-ready applications using spreadsheets as your data source.

These docs will help you get set up, understand how Sheet Ninja works, and build reliable applications on top of Google Sheets.
