Opera Software ASA

Opera can import contacts from Outlook Express, Thunderbird, Eudora, Netscape 6/7 and old versions of Opera.

In Opera on Windows or Unix, from the menu, select Settings > Import and export > Import mail

For Mac and Opera versions 9 and below, from the menu, select File > Import and export > Import mail

If you need to import contacts from other programs you can try software such as Dawn, which can convert contacts for a number of different programs.

An alternative is to use this online service which will convert comma-separated or tab-delimited contact files to Opera's contacts format: www.hallvord.com/opera/conversion1.htm
