CSV is a mess!

The CSV should be comma separated, not semi-colon

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.
