Closes #660
Why is this the best possible solution? Were any other approaches considered?
Previously, an error about a missing sheet name may be thrown, e.g. if the form didn't contain any regular choices. This change explicitly checks for file extension, in order to show a nicer error message. The existing constants, aliases, and validation pattern are used.
What are the regression risks?
I think this is just an enhancement, since the old behaviour was confusing, and in both cases an error is raised.
