A method, for a digital computer having a memory and a processor for executing a program, for creating and importing data into a form viewable by a user of a data processing system, comprising the steps of: (a) importing data exported from an end user application and populating one or more data fields in the viewable form with the imported data; (b) performing calculations on the imported data and rule conditions required to fill in the form, the calculations and rule conditions being in a form file created with a form designer; (c) allowing the user to review and change the imported data; and (d) outputting the viewable form. A data processing system, on a digital computer having a memory and a processor for executing a program, for creating and importing data into a form viewable by a user, comprising: (a) a form file, comprising a model of the form and capable of calculations and rule conditions required to fill in the form; (b) a data file comprising data exported from an end user application program; and (c) a viewer program capable of executing in the memory and directing the processor to generate the viewable form, to import the exported data to populate one or more data fields in the form with the imported data, to allow the user of the data processing system to review and change the imported data, and to perform the calculations on the imported data.
