I need a spreadsheet program that can: 1. Operate cross platform (my IT guys PC, Im Mac) 2. Sort capabilities to five, ideally six, levels 3. Capable of using macros 4. Can convert spreadsheets for an html (online) environment I founded a national grassroots movement thats gone viral. We list registered supporters on our site, using Google Apps forms, the copy the content into an Excel spreadsheet. A friend out of state (PC user) is able to work magic with macros that magically sorts, fixes, and converts the lists to appear in our online directory (you can see an example at http://www.the350project.net/states/states_a-d.html). I created the graphics; he somehow builds the page using those plus the spreadsheets. This is something I really need to be able to do on my end, as the owner of the site, but MS took macros out of the Mac version of Office Excel....OpenOffice only sorts three levels, and he says we need at least five.... Since I have no intention of becoming a PC user, I need to find a software program that will work on a Mac and still be able to do all this. I realize many (most?) software programs are capable of opening and saving .xls files, but the multi-level sort, macros, and html are critical to any of this working, according to him. Suggestions? Help? Someone I should talk to? Thanks in advance, folks. Much appreciated!
