XLSXReader is a heavily modified version of:
SimpleXLSX php class v0.4 (Artistic License)
Created by Sergey Schuchkin from http://www.sibvision.ru - professional php developers team 2010-2011
Downloadable from GitHub.
Key Changes include:
Separation into two classes - one for the Workbook and one for Worksheets
Access to sheets by name or sheet id
Use of ZIP extension
On-demand access of files inside zip
On-demand access to sheet data
No storage of XML objects or XML text
When parsing rows, include empty rows and null cells so that data array has same number of elements for each row
Configuration option for removing trailing empty rows
Better handling of cells with style information but no value
Change of class names and method names
Removed rowsEx functionality including extraction of hyperlinks
