great PHP Class for fast parsing output from XLSX files!
I'm working on a application where people can fill in a HTML form and i feed those values to the XLSX and output the results. Currently this is working with PHPExcel, but it's really slow on this point.
When i just read the XLSX files with the default values the SimpleXLSX class reads it in just a fraction of a second, but i can't set cell values dynamically.
Is there any way to use this class with setting custom/dynamically cellvalues which are being used to calculate formulas and change the output?
