Out-FancyHTML Function


For a larger project of mine, I needed to produce some fancy looking HTML reports from the data I collected.  An example of this output can be seen below.:



The screen shot shows the results of the code below running on my local laptop:

Get-Process | Select Name, CPU, Handles, Path, Company, FileVersion | Sort Name



The code takes the results of any table based output, formats it as a HTML table, then runs various colour highlighting on specific cells depending on the rules you specify.

For example, the following code will find any cell in the “Handles” column and checks the values found.  If the value is between 50 and 100, it will be coloured in pale yellow (#FFFFC0)

$html = Set-CellColour -InputObject $html -Filter 'Handles -lt 100 -and Handles -gt 50' -Colour '#ffffc0'

Several colour filters can be applied as shown in the code below.



The following code will produce something similar, and will get you on your way, you can also download it below…

# Need to set some variables first....
[string]$dt1    = (Get-Date -Format 'yyyy/MM/dd HH:mm')
[string]$un     = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name.ToLower()
[string]$server = '[server/report name here]'
[string]$report = '[report name here]'

    I grabbed your HTML report and tried sticking it into an Outlook 2010 HTML email. Unfortunately the renderer is known not to be very good… and chokes and messes up the otherwise pretty layout.

    Something to keep in mind for others who are looking for reports they can email.

      Thanks Cody. If ever I want to share code, I never rely on HTML mail as it will always screw up code.
      Paste it into a plain text editor (like Notepad) and add it as an attachment.

  2. Hi, while this module may not have the freedom, it does have the ease of creating HTML reports without having to write any html code in your powershell script. Check out the link for examples and code.

    Hi There,

    I’m having some trouble with this function.

    When I try to set the filter it runs but doesn’t out-file the HTML file

    If I comment out the filter, it out-files the HTML just fine.

    I’m stumped. Any help would be appreciated, thanks.
