## 💬 A note on versions

Functions like XLOOKUP, FILTER, LET and TEXTSPLIT need **Excel 2021 or Microsoft 365**. Where an older alternative exists, the notes show it too. ✅

## 🚀 Why this book works

Most Excel guides are long and dry. These notes are **short, visual and practical**: one idea per page, a clear example, and a task to try. By the end you should be able to clean messy data, analyse it, summarise it, chart it, and present it. 📈✨

**Happy learning and happy analysing! 🎉📚**
