Overview

Excelwind lets you generate Excel files using JSX syntax and Tailwind-style classes, backed by ExcelJS. It runs in JavaScript runtimes with Node compatibility and does not rely on React or any browser APIs.

What you get

• Declarative JSX for worksheets, rows, and cells
• Tailwind-style utility classes via className or excelwindClasses
• Templates that load existing Excel files
• Images, named ranges, and processors for advanced layouts
