An input value cell or an expected value cell is normally handled by parsing the cell contents based on the value type. Special processing of cell contents is implemented by a set of classes known as cell handlers. There is a variety of cell handlers provided (*list them*), and you can write your own (*show example*).

The cell handlers currently active are defined in Cell Handler Lists.

These are the standard cell handlers for the core Fit fixtures:

• Exception Keyword Handler
• Fail Keyword Handler
• Symbol Handlers

These are some additional cell handlers provided that you can add to a list if you need them:

• Floating Point Handler
• Guid Handler
• Reg Ex Handler
• String Handler
