Data for your simulation can be uploaded from a file rather than keyed in. This feature also enables you to upload up to 1,000 items. To use this feature a valid license key is required. License keys are available in a variety of plans and are available by clicking here.

You may want to validate your file before purchasing a license key. To do this browse for the file you want to validate and then press Validate.


Submitted files must be in comma delimited text format (csv) with no header row and with the following fields in the following order (item name, low estimate, medium estimate, high estimate and percentage probability):

Field Name



Max Length

Item Name

The name of the item



Low Estimate

The low estimate for the item



Med Estimate

The medium estimate for the item



High Estimate

The high estimate for the item




The percentage probability of the item being between the low and medium estimates
