  Existing approaches for detecting anomalies in spreadsheets can help to
discover faults, but they are often applied too late in the spreadsheet
lifecycle. By contrast, our approach detects anomalies immediately whenever
users change their spreadsheets. This live inspection approach has been
implemented as part of the Spreadsheet Inspection Framework, enabling the tool
to visually report findings without disturbing the users' workflow. An advanced
list representation allows users to keep track of the latest findings,
prioritize open problems, and check progress on solving the issues. Results
from a first user study indicate that users find the approach useful.
