Function Add-ConditionalFormatting { <# .Synopsis Adds conditional formatting to worksheet. .Description Conditional formatting allows excel to * Mark cells with Icons depending on their value * Show a databar whose length indicates the value or a 2 or 3 color scale where the color indicate the relative value * Change the color, font, or number format of cells which meet given criteria Add-ConditionalFormatting allows these to be set; for fine tuning of the rules you can use the -PassThru switch, which will return the rule so that you can modify things which are specific to that type of rule, for example the values which correspond to each icon in an Icon set. .Example > PS> $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 "b2: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 conditionally formatted (excluding the top row) to show red text if the columns contain "2003" or "Disabled respectively. A fixed date format is then applied to columns D..G, and the top row is formatted. Finally the workbook is saved and the Excel object closed. .Example > >PS $r = Add-ConditionalFormatting -WorkSheet $excel.Workbook.Worksheets[1] -Range "B1:B100" -ThreeIconsSet Flags -Passthru $r.Reverse = $true ; $r.Icon1.Type = "Num"; $r.Icon2.Type = "Num" ; $r.Icon2.value = 100 ; $r.Icon3.type = "Num" ;$r.Icon3.value = 1000 Again Export-Excel has been called with -passthru leaving a package object in $Excel This time B1:B100 has been conditionally formatted with 3 icons, using the flags icon set. Add-ConditionalFormatting does not provide access to every option in the formatting rule, so passthru has been used and the rule is modified to apply the flags in reverse order, and boundaries for the number which will set the split are set to 100 and 1000 .Example Add-ConditionalFormatting -WorkSheet $sheet -Range "D2:D1048576" -DataBarColor Red This time $sheet holds an ExcelWorkseet object and databars are add to all of column D except for the tip row. .Example Add-ConditionalFormatting -Address $worksheet.cells["FinishPosition"] -RuleType Equal -ConditionValue 1 -ForeGroundColor Purple -Bold -Priority 1 -StopIfTrue In this example a named range is used to select the cells where the formula should apply. If a cell in the "FinishPosition" range is 1, then the text is turned to Bold & Purple. This rule is moved to first in the priority list, and where cells have a value of 1, no other rules will be processed. #> Param ( #A block of cells to format - you can use a named range with -Address $ws.names[1] or $ws.cells["RangeName"] [Parameter(Mandatory = $true, Position = 0)] [Alias("Range")] $Address , #The worksheet where the format is to be applied [OfficeOpenXml.ExcelWorksheet]$WorkSheet , #A standard named-rule - Top / Bottom / Less than / Greater than / Contains etc. [Parameter(Mandatory = $true, ParameterSetName = "NamedRule", Position = 1)] [OfficeOpenXml.ConditionalFormatting.eExcelConditionalFormattingRuleType]$RuleType , #Text colour for matching objects [Parameter(ParameterSetName = "NamedRule")] [Alias("ForeGroundColour")] [System.Drawing.Color]$ForeGroundColor, #Colour for databar type charts [Parameter(Mandatory = $true, ParameterSetName = "DataBar")] [Alias("DataBarColour")] [System.Drawing.Color]$DataBarColor, #One of the three-icon set types (e.g. Traffic Lights) [Parameter(Mandatory = $true, ParameterSetName = "ThreeIconSet")] [OfficeOpenXml.ConditionalFormatting.eExcelconditionalFormatting3IconsSetType]$ThreeIconsSet, #A four-icon set name [Parameter(Mandatory = $true, ParameterSetName = "FourIconSet")] [OfficeOpenXml.ConditionalFormatting.eExcelconditionalFormatting4IconsSetType]$FourIconsSet, #A five-icon set name [Parameter(Mandatory = $true, ParameterSetName = "FiveIconSet")] [OfficeOpenXml.ConditionalFormatting.eExcelconditionalFormatting5IconsSetType]$FiveIconsSet, #Use the icon set in reverse order, or reverse the orders of Two- & Three-Color Scales [Parameter(ParameterSetName = "NamedRule")] [Parameter(ParameterSetName = "ThreeIconSet")] [Parameter(ParameterSetName = "FourIconSet")] [Parameter(ParameterSetName = "FiveIconSet")] [switch]$Reverse, #A value for the condition (for example 2000 if the test is 'lessthan 2000'; Formulas should begin with "=" ) [Parameter(ParameterSetName = "NamedRule")] $ConditionValue, #A second value for the conditions like "between x and Y" [Parameter(ParameterSetName = "NamedRule")] $ConditionValue2, #Background colour for matching items [Parameter(ParameterSetName = "NamedRule")] [System.Drawing.Color]$BackgroundColor, #Background pattern for matching items [Parameter(ParameterSetName = "NamedRule")] [OfficeOpenXml.Style.ExcelFillStyle]$BackgroundPattern = [OfficeOpenXml.Style.ExcelFillStyle]::None , #Secondary colour when a background pattern requires it [Parameter(ParameterSetName = "NamedRule")] [System.Drawing.Color]$PatternColor, #Sets the numeric format for matching items [Parameter(ParameterSetName = "NamedRule")] $NumberFormat, #Put matching items in bold face [Parameter(ParameterSetName = "NamedRule")] [switch]$Bold, #Put matching items in italic [Parameter(ParameterSetName = "NamedRule")] [switch]$Italic, #Underline matching items [Parameter(ParameterSetName = "NamedRule")] [switch]$Underline, #Strikethrough text of matching items [Parameter(ParameterSetName = "NamedRule")] [switch]$StrikeThru, #Prevent the processing of subsequent rules [Parameter(ParameterSetName = "NamedRule")] [switch]$StopIfTrue, #Set the sequence for rule processing [int]$Priority, #If specified pass the rule back to the caller to allow additional customization.
