Extract text from Script files (QDL)
To convert QDL Scripts to another format, you need Notepad++ or other Developer software.
To convert other file formats to the "Source Code File" file type, you need software like Notepad++ or a similar tool.
A .QDL file is a plain text source code file written in the Cue Description Language or the Quick and Dirty Language (QDL). It is primarily designed to be a human-readable, easily parsed scripting language for automation, server-side claim management, and aggregate processing.
Because .QDL files are stored in unencrypted plain text, they can be opened and edited using robust developer text editors like Notepad++ or Visual Studio Code. However, the specific syntax - which heavily features rank polymorphism, monadic operators, and stem aggregates - is meant to be executed by a dedicated QDL runtime environment.
The main disadvantage of the .QDL format is its obscure extension. Microsoft Windows and macOS do not natively recognize the file, prompting confusing "How do you want to open this file?" dialogs. Furthermore, sharing a raw script file over enterprise networks often triggers email security filters that aggressively block unfamiliar executable code.
To make the file accessible to non-developers, converting the .QDL to TXT or MD (Markdown) is highly recommended. This allows anyone to read the code without triggering operating system execution warnings. You can also format the output as a PDF if the script needs to be shared as a static, uneditable document. When converting, you lose the ability to directly execute the file in a compiler, but the text data remains 100% intact.
Convert.Guru analyzes your QDL file, detects the exact format, and lets you read the text inside.
If you want to convert QDL file to TXT, RTF, DOC, DOCX, ODT, PAGES, TEX, LATEX, MD, MARKDOWN, LOG or NFO, you can use Notepad++ or similar software from the "Script Execution and Programming" category. In the File menu, look for Save As… or Export….
To convert PDF, DOC, ASC, TODO, NFO, MEMO, README, DOCX, JPG, TXT, NOTE or RTF files to QDL, try Notepad++ or another comparable tool in the "Script Execution and Programming" 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 QDL converter.
