How do I correct problems with Bools in Excel CSV files?
If you work in Excel with a CSV file that contains Bools, Excel uppercases the Bools, interpreting them as the built-in functions TRUE() and FALSE(). This cannot be changed by using either a retype or find/replace. However, the application expects lowercase true and false, and throws an exception if the uppercase tokens are passed. Workaround: After you finish working in Excel, save the file, close Excel, and open the CSV file in a text editor. Replace TRUE with true and FALSE with false.
