You're sold, but you've invested a lot of time into your spreadsheet models, and you don't want to move them into a new tool yet. That's okay — you can now account for uncertainty without leaving your spreadsheet, with the Causal Scenarios add-on for Google Sheets.
How it works
Causal Scenarios lets you define ranges for your model's assumptions, and the add-on runs hundreds of simulations to show you the range of possible scenarios.
Step 1: Define your inputs
Your model will have various uncertain assumptions. For each, select its cell and enter the plausible range of values that the assumption could take on.
Step 2: Select your outputs
Select a cell or range of cells for the main outputs of your model.
Step 3: Run the simulation
Causal uses your input ranges to run simulations, determining the range of possible values for your outputs.
