Function Add-ConditionalFormatting {
<#
.Synopsis
    Adds contitional formatting to worksheet
.Example
    $excel = $avdata | Export-Excel -Path (Join-path $FilePath "\Machines.XLSX" ) -WorksheetName "Server Anti-Virus" -AutoSize -FreezeTopRow -AutoFilter -PassThru
 
    Add-ConditionalFormatting -WorkSheet $excel.Workbook.Worksheets[1] -Address "b":b1048576" -ForeGroundColor "RED" -RuleType ContainsText -ConditionValue "2003"
    Add-ConditionalFormatting -WorkSheet $excel.Workbook.Worksheets[1] -Address "i2:i1048576" -ForeGroundColor "RED" -RuleType ContainsText -ConditionValue "Disabled"
    $excel.Workbook.Worksheets[1].Cells["D1:G1048576"].Style.Numberformat.Format = [cultureinfo]::CurrentCulture.DateTimeFormat.ShortDatePattern
    $excel.Workbook.Worksheets[1].Row(1).style.font.bold = $true
    $excel.Save() ; $excel.Dispose()
 
    Here Export-Excel is called with the -passThru parameter so the Excel Package object is stored in $Excel
    The desired worksheet is selected and the then columns B and i are conditially formatted (excluding the top row) to show
    Fixed formats are then applied to dates in columns D..G and the top row is formatted
    Finally the workbook is saved and the Excel closed.

Function Set-Format {
<#
.SYNOPSIS
    Applies Number, font, alignment and colour formatting to a range of Excel Cells
.EXAMPLE
    $sheet.Column(3) | Set-Format -HorizontalAlignment Right -NumberFormat "#,###"
    Selects column 3 from a sheet object (within a workbook object, which is a child of the ExcelPackage object) and passes it to Set-Format which formats as an integer with comma seperated groups
.EXAMPLE
    Set-Format -Address $sheet.Cells["E1:H1048576"] -HorizontalAlignment Right -NumberFormat "#,###"
    Instead of piping the address in this version specifies a block of cells and applies similar formatting
