Question

我需要将数据添加到CSV文件的最后一列。我拥有的测试文件如下：

NAME,AGE,OFFICE,DEPT,SKILL
jack,24,IBM,Retail
tom,32,MS,BFSI
SAM,44,MGR,Test

我设法解析了CSV，但是很难将数据添加到最后一列“ SKILL”。要求是将单词“ Java”添加到每一行的最后一列

NAME,AGE,OFFICE,DEPT,SKILL
jack,24,IBM,Retail,Java
tom,32,MS,BFSI,Java
SAM,44,MGR,Test,Java

请注意，添加到最后一列的值在各行中保持不变。

Answer 1

您可以更改导入对象的SKILL属性值，并通过以下方法导出到CSV文件：

Import-Csv test.txt |
    ForEach-Object {$_.SKILL = "Java"; $_} |
    Export-Csv test_out.txt -NoTypeInformation

但是Export-Csv会在值周围加上引号，因此test_out.txt看起来像这样：

"NAME","AGE","OFFICE","DEPT","SKILL"
"jack","24","IBM","Retail","Java"
"tom","32","MS","BFSI","Java"
"SAM","44","MGR","Test","Java"

也许您应该简单地在每行第二行的末尾添加",Java“：

Get-Content test.txt |
    ForEach-Object { if($_.ReadCount -gt 1) { "$($_),Java" } else { $_ } } |
    Out-File test_out.txt

您可以简单地创建一个包含当前csv数据的对象，并使用字符串Java扩展该对象，如下所示：

$results = @() # Empty array to store new created rows in
$csv = Import-Csv "$PSScriptRoot\csvfile.csv"
foreach ($row in $csv) {
    $properties = [ordered]@{
        NAME   = $row.NAME
        AGE    = $row.AGE
        OFFICE = $row.OFFICE
        DEPT   = $row.DEPT
        SKILL  = "Java"
    }
    # insert the new row as an object into the results-array
    $results += New-Object psobject -Property $properties
}
# foreach-loop filled the results-array - export it as a CSV-file
$results | Export-Csv "new-file.csv" -NoTypeInformation

如何使用PowerShell将数据添加到CSV的最后一列？
