# Import a spreadsheet

> Bring planning data from an Excel or CSV file into a workspace: inspect, map, check as a dry run, review the proposed changes and apply them only when you confirm.

## Steps

1. Upload an XLSX or CSV file under **Imports**.
2. The platform inspects every sheet. Formulas without cached values are flagged; macros and external links are
   detected and never run or followed.
3. Map cells and tables to planning inputs.
4. Validate: a dry run shows what would change without changing anything.
5. Review the proposed changes and apply them with an explicit confirmation. An applied import can be reversed.

## Good to know

- Nothing is written before you confirm.
- Each applied import is recorded in the audit log with who applied it.
- Pricing simulations exported to Excel or PDF can be imported again under **Planning → Pricing simulations**.
