### A Brief Word about the Advanced Value Binder
When loading data from a file that contains no formatting information, such as a CSV file, then data is read either as strings or numbers (float or integer). This means that PHPExcel does not automatically recognise dates/times (such as "16-Apr-2009" or "13:30"), booleans ("TRUE" or "FALSE"), percentages ("75%"), hyperlinks ("http://www.phpexcel.net"), etc as anything other than simple strings. However, you can apply additional processing that is executed against these values during the load process within a Value Binder.

A Value Binder is a class that implement the PHPExcel_Cell_IValueBinder interface. It must contain a bindValue() method that accepts a PHPExcel_Cell and a value as arguments, and return a boolean true or false that indicates whether the workbook cell has been populated with the value or not. The Advanced Value Binder implements such a class: amongst other tests, it identifies a string comprising "TRUE" or "FALSE" (based on locale settings) and sets it to a boolean; or a number in scientific format (e.g. "1.234e-5") and converts it to a float; or dates and times, converting them to their Excel timestamp value – before storing the value in the cell object. It also sets formatting for strings that are identified as dates, times or percentages. It could easily be extended to provide additional handling (including text or cell formatting) when it encountered a hyperlink, or HTML markup within a CSV file.
