Write log to csv file

Hi,

In my script I try to write logs to a file. I use something like this in the processing loop:

$sReport += "$fromValue,$toValue,$result`r`n"

At the end, I do:

$sReport | out-file "Report.csv"

But when I open the file in Excel, all content are in 1 column, instead of 3. Could you help?

Thanks,

Yong
