We have a very complex excel spreadsheet that has kind of gotten out of hand. It's currently over 256 MB in size and takes over 1/2 hour to open on an Intel i3 with 8gb of ram and a zippy AMD SSD SATA drive. A full half hour. Ugh.
This file has multiple calls to several different sheets for computing dates, times, and more fancy calculations.
I have heard from others that there is a way to upload this file to our server and keep the calculations but speed up the process 1000x by using PHP. Is that true?
I have general PHP experience using My SQL and can code up a site pretty easily, but the conversion is where I'll need the most help. If that's enough info, please let me know. If not, just ask! I've got six months to put this together which I'm assuming is plenty of time. Thanks!
