Thar is sad to hear - but who hasn’t been there ?
Doesn’t the database loader give a useful warning/error ?
What is the difference between “to”, “fo”, “io”, “tu” ?
They are all typos, spelling errors.
What is the “real name” ? “To” or “to” ?
My suggestion would be to use a (naming) convention here - the same problem hits me all the time.
“CamelCase" or “snake_case" or “UPPERCASE" or “lowercase”  ?
None of my compilers is intelligent to figure out how to fix this typos - and that is a good thing.

And: Helping colegues to find this kind of bugs puts people together.
Exchange knowledge, chat about other stuff.
Best practise, new projects, problems, even the solved ones.

The first pass should still use strcmp() in case some IOC has choices (in mbbo strings) that only differ by case, but the second pass would accept the first to match even when the cases differ.
