This document summarizes a talk given by the authors of the paper "Automatically Inferring ClassSheet Models from Spreadsheets". The talk highlights that the paper from 10 years ago was the authors' first paper presented at VL/HCC and influenced much of their subsequent research. It influenced many students who worked on related topics. The approach presented in the paper was novel but had some limitations that motivated the development of ClassSheets, which model spreadsheets in an object-oriented way. The work has been widely cited and influenced several other works on spreadsheet modeling, analysis, and migration.
