I solved problem using cache to file.
Unfortunately extracting file takes more than 4 minutes and each calculate also, so if almost whole spreadsheet is fed by formulas it's pointless to use PHPExcel to analyze whole file.
Problem of time can be easy solved if you could use that cached files time by time not only once on each script run but honestly u can't.
