No, that's the default behaviour of export-csv. It will put double quotes for any value or property names (header) that contain spaces.

### Writes CSV, but stupid export-csv does so with quotes around every field
$temp | export-csv -notype "d:\reports\name_of_file.csv"

### Reads the output from export-csv, gets rid of the quotes, and rewrites the file
$text = gc "d:\reports\name_of_file.csv"
$text = $text -replace('"','')
$final = [String]::Join([Environment]::NewLine, $text)
[System.IO.File]::WriteAllText("d:\reports\name_of_final", $final)


it's ugly, but it will get you a .csv with no quotes.

just for clarification, the replace statement is a single quote, double quote, single quote, comma, two single quotes.

this can be simplified by:
$file = "file.csv"
(gc $file) -replace('"','') | Out-File $file -Force
