Thomas Schmitz and Dietmar Jannach used the email communication within the ENRON company to identify faults in the Enron corpus. They have found 36 faults, which they published on their website.

We have created a properties file for each spreadsheet which indicates the faulty cell(s) so that the spreadsheets can be used in automatic evaluations. The properties files follow a certain  format and can be downloaded here.

If you want to cite this corpus, please refer to the original paper.
