Question

我使用我的FireFox扩展程序中的javascript成功写入Excel文件。我可以获得我想要的格式和内容，但是我遇到了障碍。

为了添加格式，我必须EOF工作簿全局流，以及BOF工作表流。当我这样做时Excel说文件已损坏。

我目前正按以下顺序将这些记录写入文件：

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

然而，当我在Excel中打开文件时它表示它已损坏，当我在OpenOffice中打开它时，它加载文档就好了，当我用ExcelFile Workbook查看器打开它以查看记录时，一切看起来都很好。

以下是我在文件开头写的代码：

    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);
excelData[excelData.length] = pack("vvvvvCCCCC", 0x00C8, 0x0001, 0x0000, 0x02BC, 0x0000, 0x0200, 0x00, 0x01, 0x00, 7); // calibri 10 bold - index 1

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

我真的怀疑问题在于BOUNDSHEET记录。但是，我也没有任何运气来解决这个问题。任何帮助将不胜感激！

Answer 1

我是上面提到的Spreadsheet :: WriteExcel Perl模块的作者。

如果您send me其中一个损坏的文件，我会为您调试它，并让您知道问题所在。

Answer 2

我建议使用John McNamara的Perl Excel Writer复制您的Excel内容。然后比较他的sw和你的二进制输出。您也可以尝试联系John寻求帮助。

我相信perl lib被认为是开源Excel文件创建的“标准”。许多其他语言的Excel编写者只是John工作的端口。

此外，您能否详细说明用于编写Excel文件的FF扩展程序？听起来不错。
