If you already have a model that you'd like to transfer from a spreadsheet, you can copy + paste it line by line. Easy!
Open your spreadsheet
Copy + paste the row you'd like to paste
Make sure the row only has one item and is divided month by monthOpen Canaree and navigate to fx the Expense tab
Create an item and unfold the custom values
Click paste and the numbers will appear - voila!

At current it's not possible to upload an entire model as the matching of each cell is nearly impossible. We've analysed 100s of models and each one is different!
Do get in touch if you'd like help transferring your model.
