使用 Powershell 添加新列并填充工作表名称

Question

我正在尝试操作下面的代码以在输出中创建一个新列并在新列中分配 sheet名称。

$param = @{
    Path       = 'C:\TEMP\Template\TemplateName.xlsx'
    StartRow   = 5
    HeaderName = 'Property', 'Current settings', 'Proposed settings'
}

# foreach worksheet in this file
Get-ExcelSheetInfo -Path 'C:\TEMP\Template\TemplateName.xlsx' | ForEach-Object {
    # set the worksheetname name in $param
    $param['WorksheetName'] = $_.Name
    # import the worksheet and enumerate it
    foreach($line in Import-Excel @param) {
        $currSettings = $line.'Current settings'
        $propSettings = $line.'Proposed settings'
        # if the value of 'Current settings' cell is equal to the value of
        # 'Proposed settings' cell OR is empty / white spaces, skip it, go to next iteration
        if($currSettings -eq $propSettings -or [string]::IsNullOrWhiteSpace($currSettings)) {
            continue
        }
        # if we're here, condition before this was not true, hence we want to
        # output this line
        $line
    }
} | Export-Excel -Path C:\Temp\Template\Changes.xlsx -AutoSize

sheet名称已分配给 $_.Name 变量，但我想将其添加到所有行旁边的新列 (A) 中。例如。取自特定 sheet 的每一行都应在 A 列中具有 sheet 名称。

您可以使用 calculated property with Select-Object 重新创建每个对象 ($line) 添加 WorksheetName 属性:

Get-ExcelSheetInfo -Path 'C:\TEMP\Template\TemplateName.xlsx' | ForEach-Object {
    $param['WorksheetName'] = $_.Name
    foreach($line in Import-Excel @param) {
        $currSettings = $line.'Current settings'
        $propSettings = $line.'Proposed settings'
        if($currSettings -eq $propSettings -or [string]::IsNullOrWhiteSpace($currSettings)) {
            continue
        }
        $line | Select-Object @{N='WorksheetName';E={$param['WorksheetName']}}, *
    }
} | Export-Excel -Path C:\Temp\Template\Changes.xlsx -AutoSize

或者，您可以将新的属性添加到现有对象，而不是重新创建它，但是这会将属性添加到最后一个位置（Excel 中的最后一列文件):

# update the object
$line.PSObject.Properties.Add([psnoteproperty]::new('WorksheetName', $_.Name))
# output the object, to be captured by `Export-Excel`
$line
