perl - 如何从 Perl 创建或读取 OpenOffice 电子表格？

Question

在 Perl 中创建和读取 OpenOffice 电子表格的好方法是什么？

Answer 1

我认为 Open Office 原生文档格式基于 OpenDocument 规范，基本上是一种 zip 压缩的 XML 格式。这是真的，您可能可以使用您选择的 perl XML 操作工具来操作它。

或者，CPAN 上有 Open Office OpenDocument 连接器模块套件，它为 OpenDocument 规范提供了高级 API。

据我所知，这些模块中的表格方法应该允许在 OO Calc 文档中读取和写入数据。

Answer 2

我使用OpenOffice::OOCBuilder创建大型颜色编码表。非常喜欢。对于更简单的任务，我经常使用任何电子表格程序都可以轻松打开的纯 CSV 格式

但是，您可能会选择 Excel 的东西来与其他人兼容。

Answer 3

OpenOffice 支持多种格式，如果您正在寻找可以读/写与 Excel 兼容的电子表格的东西，请查看Spreadsheet::ParseExcel进行阅读，并使用Spreadsheet::WriteExcel进行写作。我都用过它们，它们非常成熟并且运行良好。

Answer 4

这是 2.4 版本，因为最新版本不稳定。尽管有时它确实适用于最新版本。这将允许 Calc 中的实时 DDE 功能，而不是操作文件。这是在 XP 上使用 Cygwin Perl，但应该与其他人一起使用。我只想说 Excel VBA 编程 API 好 10 倍，而混乱少 10 倍。这很糟糕。

$Stardesktop = $objServiceManager->createInstance("com.sun.star.frame.Desktop");

# $Stardesktop->terminate();exit; # will kill ALL OpenOffice docs!!!

$sortDx->[3]->{Value} = $unoWrap;
#$sortDx->[3]->{Value} = \@fields; # You would think this would work? It doesn't.
$range->sort($sortDx);


# create a new sheet to paste to
$calc->getSheets->insertNewByName("NewSheet", 1 );
$sheet2 = $calc->getSheets->getByIndex(1);
$calc->CurrentController->Select($sheet2);

# copy row
$pasteHere = $sheet2->getCellByPosition(0, 0)->CellAddress;
$copyRange = $oSheet->getCellRangeByName("A1:Q1")->RangeAddress;
$oSheet->copyRange($pasteHere, $copyRange);

$cellValue = $sheet2->getCellByPosition(16, $row)->getValue()); # get cell value as integer
$date = $sheet2->getCellByPosition(5, $row)->getString(); # must get dates as strings

$calc->getCurrentController->getFrame->getContainerWindow()->setVisible(1); # set visible
$calc->close(0); # close program window
#print Win32::OLE->LastError, "\n";
