Extract text from script files (NVDL)
To convert NVDL scripts to another format, you need Oxygen XML Editor or other Developer software.
To convert other file formats to the "XML Schema Script" file type, you need software like Oxygen XML Editor or a similar tool.
The .NVDL file is an XML-based script representing the Namespace-based Validation Dispatching Language. Standardized by the International Organization for Standardization, it acts as a router for compound XML documents. It directs specific namespaces within an XML file to their corresponding external schemas (such as RELAX NG, W3C XML Schema, or Schematron) for accurate, modular validation.
Because it is a niche developer format, managing .NVDL files outside of specialized environments like Oxygen XML Editor is frustrating. Standard web browsers and office software will not execute these scripts natively. They appear as a dense wall of markup to non-technical users. The format is highly specialized, meaning your team must possess technical XML parsing knowledge and specific IDEs to make use of the raw file.
The most practical targets for conversion are standard XML or TXT files. Converting to TXT ensures the raw markup can be viewed safely on any device without triggering parser errors. While developers sometimes look to convert the syntax to standard XSD or RNG schemas, standard online converters fail to process it because .NVDL contains routing logic, not traditional schema definitions. You will lose the multi-namespace dispatching capability if you attempt to flatten it into a single schema.
This is a strict, proprietary developer format that is difficult to open or convert functionally outside of an enterprise XML stack. Often, only a compliant DSDL-aware parser can properly read or execute the data. Our engine can parse the structure, show you the raw text, and extract the underlying embedded content so you can continue your work.
Convert.Guru analyzes your NVDL file, detects the exact format, and lets you read the text inside.
If you want to convert NVDL file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Oxygen XML Editor or similar software from the "XML Namespace Validation Routing" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to NVDL, try Oxygen XML Editor or another comparable tool in the "XML Namespace Validation Routing" category.
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 NVDL converter.
