# Room for error?
Exerica not only accurately structures financial data, it can also spot and fix mistakes in original reports!
If, for example, a discovered mathematical relationship works for one column in a table and not for another, then there must be something wrong with the latter. If there is an error in one or two digits Exerica can fix it. Any legible document will be processed accurately by Exerica. That said, there might be issues with poorly scanned reports.
