I have big excel file (about 50 mb). it performs a lot of calculations. there is worksheet 1 where i put up to 15 inputs and based on inputs chosen i get result in several cells.
the idea is the following i want people be able to enter those 15 inputs on the website, then press button "give me result"
once they press button, inputs go to xls file (on server), xls file does calculations and returns result (it takes some about second to give result when i do this on my computer), Result should appear on a new page. Result should be in html format and it will consist of information taken from several xls cells. Some cells will just show inputs chosen. While 1 cell will show result of calculation (which is the price of flat in area).
of course i plan that hundreds of people will be using website and getting information. several people may apply for calculation at once.
my site is done in wordpress environment
