QT equivalency of perl's pack to EXCEL binary file

[patrik08]

I wand to try to stream binary as excel file from a QAbstractItemModel whitout activex on linux.
people dont like import CSV data... on excel on new Office excel this is a long way, only OpenOffice can import faster csv.


i found this php/perl way:

How i can Encapsulate this on a file?

//////  write function as perl/php
 
 function xlsBOF() {
    echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);  
    return;
}
 
function xlsEOF() {
    echo pack("ss", 0x0A, 0x00);
    return;
}
 
function xlsWriteNumber($Row, $Col, $Value) {
    echo pack("sssss", 0x203, 14, $Row, $Col, 0x0);
    echo pack("d", $Value);
    return;
}
 
function xlsWriteLabel($Row, $Col, $Value ) {
    $L = strlen($Value);
    echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L);
    echo $Value;
return;
}

//////  write function as perl/php

 function xlsBOF() {
    echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);  
    return;
}

function xlsEOF() {
    echo pack("ss", 0x0A, 0x00);
    return;
}

function xlsWriteNumber($Row, $Col, $Value) {
    echo pack("sssss", 0x203, 14, $Row, $Col, 0x0);
    echo pack("d", $Value);
    return;
}

function xlsWriteLabel($Row, $Col, $Value ) {
    $L = strlen($Value);
    echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L);
    echo $Value;
return;
}
