As excel columns range from A to ZZ this may be an even simpler approach:

function excel_column($col_number) {
if( ($col_number < 0) || ($col_number > 701)) die('Column must be between 0(A) and 701(ZZ)');
if($col_number < 26) {
return(chr(ord('A') + $col_number));
} else {
$remainder = floor($col_number / 26) - 1;
return(chr(ord('A') + $remainder) . excel_column($col_number % 26));
}
}

Function to convert a column number to the Excel column format.
For example:
0 = 'A';
1 = 'B';
2 = 'C'; ...
10 = 'K'; ...

I wrote it until 'NZ', but you can continue...

function excel_column($col_number){
$xls_columns=array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P',
