PowerShell 脚本检查并跳过具有黄色单元格、灰色单元格或空白单元格的行

Question

我需要准备 Powershell 脚本来检查我的 NSG 规则设计表并跳过包含黄色单元格、灰色单元格或空白单元格的行。我已经准备了下面的脚本，但它没有按预期工作。有人可以帮我修复这个脚本吗？

Powershell 脚本：

# Load the EPPlus library
Add-Type -Path "/home/lokesh/EPPlus.dll"  # Replace with the path to your EPPlus.dll file

# Create an Excel package object
$excelPackage = New-Object OfficeOpenXml.ExcelPackage

# Load the Excel file
$filePath = "/home/lokesh/NSG_Rules.xlsx"
$excelPackage = [OfficeOpenXml.ExcelPackage]::Load($filePath)

# Get the first worksheet from the Excel package
$worksheet = $excelPackage.Workbook.Worksheets[0]  # Change the index if needed

# Define a function to check cell color
function IsYellow($cell) {
    return ($cell.Style.Fill.BackgroundColor.Rgb -eq "FFFFFF00")  # Yellow color code
}

# Skip rows with yellow, gray, or blank cells
$rowsToKeep = @()
foreach ($row in $worksheet.Cells.Rows) {
    $skipRow = $false
    foreach ($cell in $row.Cells) {
        if (IsYellow($cell) -or $cell.Style.Fill.BackgroundColor.Rgb -eq "FFA9A9A9" -or -not $cell.Value) {
            $skipRow = $true
            break
        }
    }
    if (-not $skipRow) {
        $rowsToKeep += $row
    }
}

Answer 1

• 您问题中的代码在几个基本方面被破坏了；是AI生成的吗？

• 解决方案如下：

  • 按要求解决了您的问题，但请注意，EPPlus .NET 库对 PowerShell 不是特别友好，而

    ImportExcel

    PowerShell 模块通常是更好的选择。
    此外，对于商业用途，EPPlus 需要付费许可证。

  • 它：

    • 收集感兴趣的（数据）行作为输出数组中的

      [OfficeOpenXml.ExcelRangeRow]

      实例以进行进一步处理；每个此类行的单元格都可以通过

      .Range

      属性进行枚举，并且每个枚举单元格都有一个

      .Value

      属性。

    • 不会创建 PowerShell 友好的 [pscustomobject]

      实例，并具有为标题单元格命名的属性，就像 Import-Excel

       中的 

      ImportExcel

       所做的那样。

    • 不会

      尝试更新电子表格本身，即它不会删除您想要跳过（省略）的行。

# Specify the license type (required in v5+ of EPPlus)
$env:EPPlusLicenseContext = 'NonCommercial'

# Load the EPPlus assembly.
Add-Type -LiteralPath "/home/lokesh/EPPlus.dll"  # Replace with the path to your EPPlus.dll file

# The file path of the workbook to open.
$filePath = "/home/lokesh/NSG_Rules.xlsx"

# Create an Excel package object and load the workbook file.
# Convert-Path ensures that a *full path* is passed, which is required in
# .NET calls, given that .NET's working dir. usually differs from PowerShell's.
$excelPackage = 
  [OfficeOpenXml.ExcelPackage]::new((Convert-Path -LiteralPath $filePath))

# Get the first worksheet from the Excel package
$worksheet = $excelPackage.Workbook.Worksheets[0]

# Iterate over all rows that have cells with content and/or formatting
# and collect the data rows of interest.
$headerProcessed = $false
[array] $rowsOfInterest = 
  foreach ($row in $worksheet.Rows) { # process each row
    $rowCellCount = 0; $skipRow = $false
    foreach ($cell in $row.Range) { # process each cell in a row
      ++$rowCellCount
      if (-not $headerProcessed) { continue } # header row: just count the cells.
      # data row: check for a background color of interest. 
      $skipRow = $cell.Style.Fill.BackgroundColor.Rgb -in 'FFFFFF00', 'FFA9A9A9'  
      if ($skipRow) { break }
    }
    if (-not $headerProcessed) { 
      # header row: Save the count of cells in the header row (assumed to be the first one),
      # i.e. the count of columns
      $headerRowCellCount = $rowCellCount
      $headerProcessed = $true
      continue
    } 
    # data row: Also check if not all cells in the rows had values.
    $skipRow = $skipRow -or $rowCellCount -lt $headerRowCellCount
    if (-not $skipRow) {
      $row # output
    }
  }

# $rowsOfInterest is now an array of [OfficeOpenXml.ExcelRangeRow] instances
# containing only those data rows that neither have empty cells nor
# cells with the specified background colors.

# Sample output: Print the address and value of the cells in these rows.
$rowsOfInterest.Range | Select-Object Address, Value
