Template planning
Decide the audience, inputs, outputs, refresh rhythm, and protected areas before building.
- Write down who will use the file and what they need to see before opening Excel -- the structure follows from that, not the other way round.
- Decide up front which cells are inputs, which are calculations, and which are outputs -- mixing them freely is the most common reason templates break later.
- Plan the refresh rhythm (daily, weekly, one-off) since it decides whether Power Query connections or a simple manual paste step is needed.
