Attention: Work with these functions is better since function Excel_LoadFile even if you need to keep nothing. By a call of this function the program remembers on expansion of a file with what type to it is necessary to work further and on it depends in what format will be preservation made.

Excel_LoadFile (' C: \\myfile.xls ');//we Open a file
$buf = Excel_ReadCell ('A',0);//It is read out cell contents in a variable buf
WriteToLog ($buf);//It is deduced contained in a broad gull 

Excel_LoadFile('.xlsx ');//It is necessary, that we will establish with what format to work
Excel_WriteCell ('A',0,'Hello world!!!');//It is written down in a cell
Excel_SaveFile ('C:\\myfile.xlsx');//It is kept in a file
