$workbook = new Spreadsheet_Excel_Writer('formula.xls');
$worksheet =& $workbook->addWorksheet();

$worksheet->write(002);
$worksheet->write(01"and");
$worksheet->write(022);

If you have the following formula in excel:

=Hoja1.B1+Hoja2.C4

you must translate to excel_writer like this:

$sheet->writeFormula($row, $col, "=Hoja1!B1+Hoja2!C4");
Note by: Bastian Hoyer
$worksheet->writeFormula(5, 0, '=VLOOKUP("John Smith",A1:A3,1,0)');

works for me.. so advanced functions should be no problem
Note by: tom@inxco.be
Note that advanced formula's like VLOOKUP do not work...

There's a builtin function to convert row & col into Excel coordinates:

Spreadsheet_Excel_Writer::rowcolToCell()

It's also worth noting that function names show be in English, i.e., you can't use localized names as in real Excel.
Note by: Le Tange
private function getLetterColumn($num)
{
if($num> 26)
{
$str = chr((($num - 1) / 26) + 64)
.chr((($num - 1) % 26) + 65);
}
else
{
$str = chr($num + 64);
}
return $str;
}

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...
