SimSheet™ adds simulation capabilities to Microsoft Excel™ spreadsheets. SimSheets are for planning applications to extend spreadsheet analysis to explore in greater depth the range and likelihood of outcomes. Typical examples are: budgeting, product pricing, sales forecasting and ROI analysis. With traditional spreadsheets, a single value is used to represent a range of possible values (i.e. estimated number of units sold for the month, labor expenses for the quarter, etc...). SimSheet™ provides new functions for Excel that allow estimates, probabilities and ranges for planning variables to be used. A SimSheet™ run uses statistical sampling techniques to generate cell values for these estimated parameters.

Other SimSheet™ functions are used to tabulate and report results from the sample spreadsheets generated dynamically. The results for any cell in the spreadsheet can be summarized and statistics such as minimum, average and maximum reported. SimSheet™ output provides visibility of the best case, most likely and worst case results based on estimates of the uncertain variables affecting a decision. The full range of Excel functions are still available for analysis, summarizing and graphing the data.
