Excel powershell转置并仅保留一组标头

excel powershell

Excel powershell转置并仅保留一组标头,excel,powershell,Excel,Powershell,我有一个如下所示的数据集 headers data ip 192.168.1.1 netmask 255.255.255.0 description class C ip 172.20.1.1 netmask 255.255.0.0 description class B ip 10.0.0.1

我有一个如下所示的数据集

headers            data
ip                 192.168.1.1  
netmask            255.255.255.0
description        class C
ip                 172.20.1.1  
netmask            255.255.0.0
description        class B
ip                 10.0.0.1  
netmask            255.255.255.0
description        class A

我如何将其转化为我的预期产出：

ip           netmask          description
192.168.1.1  255.255.255.0    class C
172.20.1.1   255.255.0.0      class B
10.0.0.1     255.0.0.0        class A

目前，我正在从CSV导入此数据，如下所示：

$data = import-csv .\data.txt -headers headers,data

如果有一个简单的方法可以在excel中实现这一点，那将是非常棒的

任何援助都将是巨大的。多谢各位

前面的答案没有使用问题中指定的数据，这个答案使用了。它也有完整的注释来解释它的功能。下面是代码的工作原理：

$newrow = @{} # newrow contains the values on an output row at any given time
$newtable = [System.Collections.ArrayList]@() # newtable contains the final output

# Loop through each row in the input data, assign oldrow to the current row
foreach($oldrow in $data) {
    # If the output row already has an ip, netmask or description, then start a new row (hashtable) and add the current row (hashtable) to output
    if ($newrow[$oldrow.headers] -ne $null) {
        Write-Host "$($oldrow.headers) Already found. Adding new row to output" -ForegroundColor Green 
        # Add the current row to the target object
        [void]$newtable.Add($(New-Object PSObject -Property $newrow))
        # Create a new empty row (hashtable)
        $newrow = @{}
    }
    # For each iteration, keep adding data
    Write-Host "Adding new entry for $($oldrow.headers)" 
    $newrow[$oldrow.headers] = $oldrow.data
}

# The final row is not added to the table within the loop, so it must be added here
Write-Host "Loop finished, adding final row to output" -ForegroundColor Green
[void]$newtable.Add($(New-Object PSObject -Property $newrow))

$newtable | select ip,netmask,description

假设遇到具有相同标题值的记录时，需要一个新行。在此之前，应将记录添加到同一行，标题值提供新的列名

过程

设置一个名为$newrow的哈希表

设置名为$newtable的ArrayList。ArrayList比标准数组更灵活，因为它们有一个

Add（）

方法

使用foreach循环遍历数据

从一个if语句开始，该语句处理如何查找包含已分配列的记录。此时，使用

写入主机

触发消息，添加旧行并设置新行。在foreach循环的第一次迭代中，由于hashtable为空，该值始终计算为false。

在

if

条件之外的块中，继续向哈希表添加值

最后，添加最后一行，然后使用“选择对象”按正确顺序打印输出
