Finding faults in Excel
A familiar situation for many: A large Excel file that includes many sheets, rows and columns – and in the end, the correct result stubbornly refuses to materialize. Troubleshooting can be complicated whenever numerous formulas and references are involved. Patrick Koch is working on the project “Debugging of spreadsheet programs (DEOS)”, funded by the FWF, which aims to simplify the search for errors. He recently received the “ACM SIGSOFT Distinguished Paper Award” for his publication on this subject.
