Question

I am successfully writing to an Excel file, using javascript from my FireFox extension. I can get the formatting, and contents that I want, however I have run into a roadblock.

In order to add the formatting, I have to EOF the Workbook Globals Stream, and BOF the worksheet stream. When I do that Excel says the file is corrupt.

I am currently writing to the file these records, in this order:

BOF Record (0x05 [Workbook])
WINDOW1 Record
1904 Record
FONT Record (x7)
XF Record (x17)
BOUNDSHEET Record
EOF Record
BOF Record (0x10 [Worksheet])
LABEL Record
EOF Record

However when I open the file in Excel it says it is corrupt, when I open it in OpenOffice it loads the document just fine, when I open it with ExcelFile Workbook viewer to see the records, all looks fine.

Here is the code that I am writing at the beginning of the file:

    excelData[excelData.length] = pack("vvvvvv", 0x809, 0x08, 0x0500, 0x05, 0x096C, 0x07C9); // BOF Workbook

excelData[excelData.length] = pack("vvvvvvvvvvv", 0x003D, 0x0012, 0x0000, 0x0000, 0x25BC, 0x1572, 0x0038, 0x0000, 0x0000, 0x0001, 0x0258); // WINDOW1
excelData[excelData.length] = pack("vvv", 0x0022, 0x0002, 0x0000); // 1904

excelData[excelData.length] = pack("vv", 0x0031, 0x0F+7);
excelData[excelData.length] = pack("vvvvvCCCCC", 0x00C8, 0x0001, 0x0000, 0x0190, 0x0000, 0x0200, 0x00, 0x01, 0x00, 7); // calibri 10 normal - index 0
excelData[excelData.length] = "Calibri";
excelData[excelData.length] = pack("vv", 0x0031, 0x0F+7);

    var L = 0;
for (var i=0; i<excelData.length; i++) {
    L = Number(L)+Number(excelData[i].length);
}
L = L+27;

var data = pack("VvC", Number(L), 0x0000, 12); // BOUNDSHEET
data = data+"data sheet 1";
excelData[excelData.length] = pack("vv", 0x0085, data.length);
excelData[excelData.length] = data;


excelData[excelData.length] = pack("vv", 0x0A, 0x00); // EOF
excelData[excelData.length] = pack("vvvvvv", 0x809, 0x08, 0x0500, 0x10, 0x096C, 0x07C9); // BOF Worksheet

I truly suspect the problem lies in the BOUNDSHEET record. However I am not having any luck figuring this one out either. Any help would be appreciated!

I am the author of the Spreadsheet::WriteExcel Perl module mentioned above.

If you send me one of the corrupt files I’ll debug it for you and let you know what the issue is.
