The fastest way to add or update many items at once.
- Open Import menu and choose the branch you want to work on.
- Click "Export this branch's menu" to download a spreadsheet of what's there now.
- Edit it in Excel: change prices, add rows for new items, adjust descriptions.
- Upload the file back.
Before anything is saved you'll see a preview showing exactly what will be added, what will be updated, and anything that will be skipped, with reasons.
Keep the ID column exactly as it is. Rows with an ID update that item; rows with a blank ID are added as new items.
