CSV is a mess!

Turn On Social is correct, the plugin doesn’t work the way it is written,but you can modify it easily. There are two lines that need to be edited in users-data-to-csv.php in the plugin directory.

Line 149 change
echo implode( ';', $headers ) . "\n"; to echo implode( ',', $headers ) . "\n";
Line 167 change
echo implode( ';', $data ) . "\n"; to echo implode( ',', $data ) . "\n";

Not sure why the author used semi-colons but it is an easy fix.
