About NNT files

The .NNT file is a legacy address book file created by Eudora, an early email client developed by Qualcomm. It stores contact names, email addresses, and phone numbers. The main disadvantage of this format is its extreme obsolescence. Qualcomm discontinued the software in 2006. .NNT files are completely unsupported by modern email clients like Microsoft Outlook or webmail services like Gmail. You cannot import them directly into a modern contact manager. To restore your contacts, you must convert the .NNT file to CSV (Comma Separated Values) or VCF (vCard). Standard online converters often fail to process this file because it is a closed, proprietary, and poorly documented format from decades ago. Often, only the original software can properly read or export the data. Since .NNT files often contain plain text email data, our analysis can detect the embedded text, allowing you to inspect the file and copy the raw contact information even if a structured conversion fails.

Convert.Guru analyzes your NNT file, detects the exact format, and lets you read the text inside.
