Get metadata column properties from all items in library. Can We Build It?!

sure if you have ever had to need to grab the metadata column values from a huge library in a SharePoint site.
Today I needed to grab specific column values from a library with over 50k rows in it. The great thing is with PowerShell you can absolutely do it. Getting the data was easy, but it took me a bit to toss the data into an array so that I could export it cleanly into a .csv file.  Originally I was just dumping it with Write-Out then piping that to Out-File command into a text file, but with Out-file it was putting each column’s value into a new line. (Apparently that’s default with Write-Out in PowerShell). So I had to bite the bullet and use the Export-CSV command. Of course I needed to move my For-Each into an array and that’s when things got fun for a while.
Anyways, got it working. As with all my scripts if you see a better way to make this go. Please leave me a comment!

Hopefully this helps and saves someone some time in the future.

Happy SharePointing.
