Powershell (Replacing White Spaces with a comma)

The object property values output tends to be tabular with varying white spaces between each column. I’m looking for a script that will allow me to:

1. Output the object property values to a file
2. Remove all white spaces encountered (regardless of the number of spaces)
3. Replace the spaces with one (1) comma

Replace isn’t the answer unless I literally define each instance of spaces and I can’t find any discernable documentation on using Regex…

-- formattting the output doesn't help either...

Any guidance / help would be appreciated
