Extract text from Nessus scripts (NASL)
To convert NASL scripts to another format, you need Tenable Nessus or other Developer software.
To convert other file formats to the "Security Script" file type, you need software like Tenable Nessus or a similar tool.
The .NASL file extension typically represents a script written in the Nessus Attack Scripting Language, a high-level interpreted language developed by Tenable. These scripts act as plugins for the Nessus vulnerability scanner, instructing the engine on how to detect specific security flaws, configuration issues, or system patches on a target network. While powerful for security auditing, .NASL files present a barrier for standard users: they are strictly code-based and cannot be "run" or fully validated without the proprietary Nessus engine, which often requires a paid subscription or specialized license. Furthermore, trying to open them directly in a standard word processor like Microsoft Word often results in formatting errors or encoding issues.
For users who need to review the code logic, document a custom security check, or share findings with non-technical stakeholders, converting the file is the most pragmatic workflow. To simply view and edit the syntax without the overhead of the Nessus suite, converting to a plain TXT file ensures compatibility with any text editor. For archiving security protocols or presenting the script in a clean, unalterable layout for reports, converting to PDF is the industry standard.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NASL converter.
