 ### Lazy Loader
 
 PHPExcel implements an autoloader or "lazy loader"<22>, which means that it is not necessary to include every file within PHPExcel. It is only necessary to include the initial PHPExcel class file, then the autoloader will include other class files as and when required, so only those files that are actually required by your script will be loaded into PHP memory. The main benefit of this is that it reduces the memory footprint of PHPExcel itself, so that it uses less PHP memory.

 ### Spreadsheet in memory
 
 PHPExcel's architecture is built in a way that it can serve as an in-memory spreadsheet. This means that, if one would want to create a web based view of a spreadsheet which communicates with PHPExcel's object model, he would only have to write the front-end code.
