  Excel 2013 (version 15) includes an add-in "Inquire" for auditing
spreadsheets. We describe the evolution of such tools in the third-party
marketplace and assess the usefulness of Microsoft's own add-in in this
context. We compare in detail the features of Inquire with similar products and
make suggestions for how it could be enhanced. We offer a free helper add-in
that in our opinion corrects one major shortcoming of Inquire.
