vba - Excel将列转换为行

Question

我有一个大的 Excel 表(大约 150 列 x 7000 行并且每天都在增长)，但需要以更好的方式提取信息。
我无法访问数据库软件，只有 Excel。
我已经设法使用普通公式获得了我想要的结果，但是文件大小几乎是 100mB(最初是 4mB)并且不可行 - 它太慢了。
我创建了一个只能部分解决问题的数据透视表。
我是 VBA 新手，所以我在这里尝试了一些示例来尝试学习，但目前大多数对我来说都太复杂了。
理论上，“Convert row with columns of data into column with multiple rows in Excel”看起来可以部分解决我的问题，但我就是无法让它运行!虽然我可以看到模块中的代码，但当我按下运行按钮时，它并没有出现在宏列表中。
这是我要开始的-

Name1   Name2   Location    Subject1    Subject2    Subject3
Fred    Jones   England     Spanish     Maths       English
Peter   Brown   Germany     English     (empty)     Maths
Erik    Strong  Sweden      Chemistry   English     Biology

要求的结果 -

Name1   Name2   Location    No.         Type    
Fred    Jones   England     Subject1    Spanish 
Fred    Jones   England     Subject2    Maths   
Fred    Jones   England     Subject3    English 
Peter   Brown   Germany     Subject1    English 
Peter   Brown   Germany     Subject3    Maths   
Erik    Strong  Sweden      Subject1    Chemistry   
Erik    Strong  Sweden      Subject2    English 
Erik    Strong  Sweden      Subject3    Biology 

有人可以帮忙吗？谢谢!

Answer 1

我想分享一个我经常使用的脚本。当您希望每个事务、事件等在单独的行上时，当您在一行上有多个事务、事件等时使用它。它采用包含相同数据类型的列(例如 Subject1、Subject2、Subject3...)，并且需要跨多行组合成一列(例如 Subject)。

换句话说，您的数据如下所示:

Name   Location   Subject1   Subject2   Subject3

看起来像这样:

Name   Location   Subject1
Name   Location   Subject2
Name   Location   Subject3

此脚本假定您的固定列位于左侧，而要组合(并拆分为多行)的列位于右侧。我希望这有帮助!
