I am trying to convert *.xlsb file into php array or *.csv file (or at least *.xls). I tried to use PHPExcel, but looks like it can not recognize what's inside this file.
I noticed, that you can rename *.xlsb file into *.zip file and then unzip it using command line unzip *.zip. And after this you will get next folders with sheet1.bin file:
Looks like this file should contain Excel cell values, but I still can not parse it using PHPExcel. Can someone help me is it even possible to parse *.xlsb files and get information from it? Or maybe it is possible to parse this sheet1.bin file?
