Executive Summary

The use of spreadsheets to capture information is widespread in industry. Spreadsheets can thus be a wealthy source of domain information. The authors propose to automatically extract this information and transform it into class diagrams. The resulting class diagram can be used by software engineers to understand, refine, or re-implement the spreadsheet's functionality. To enable the transformation into class diagrams they create a library of common spreadsheet usage patterns. These patterns are localized in the spreadsheet using a two-dimensional parsing algorithm. The resulting parse tree is transformed and enriched with information from the library.
