Functional Description

As you may know, file format of Microsoft® Office™ Excel™ became open since 2007 and it is based on standard OpenXML SpreadsheetML. Briefly speaking, file with .xlsx extension is just a zip archive with set of XML files. Directory structure of this file and XML files format are substitute of this standard.

eiseXLSX works in the following way:

1. class constructor reads uploaded file, preliminary uploaded template file or a directory with unzipped content
2. when you manipulate data it changes corresponding XML nodes in memory using SimpleXML and DOM
3. to save changed template you need to call Output() method – it will send data to the script output or save it as a file on a server.
