## Project Overview

`csv2excel` is a Go CLI tool that converts one or more CSV files into a single Excel (.xlsx) file, placing each CSV as a separate worksheet.

## Build

This project uses [Mage](https://magefile.org/) (`magefiles/` — eigenes Go-Modul).

```bash
mage Build         # aktuelles OS (auto)
mage BuildWindows  # dist/csv2excel.exe
mage BuildLinux    # dist/csv2excel
mage Install       # nach $GOBIN
mage Clean         # dist/ entfernen
```

Ohne Mage: `go build -o dist/csv2excel.exe .`
