Extract text from ISL files
To convert your ISL file to another format, you need Inno Setup or other Developer software.
To convert other file formats to the "Configuration & Styling" file type, you need software like Inno Setup or a similar tool.
The .ISL extension is a classic example of a "namespace collision" in the file world, primarily serving two distinct developer communities. Most commonly, it represents an Infragistics Style Library, an XML-based format used by Infragistics App Stylist to skin Windows Forms applications. These files allow developers to separate UI design from logic, similar to CSS for the web. Alternatively, it serves as an Inno Setup Language file, a simple text-based format used by the open-source Inno Setup compiler to localize installers into different languages (e.g., Spanish.isl).
The catch for .isl files is their ambiguity. Without checking the internal header, you cannot know if you are dealing with a structured XML style sheet, a plain text translation list, or a proprietary binary script from legacy software like InstallShield or game data from titles like Jurassic World Evolution. Trying to double-click an .isl file usually leads to a "Windows cannot open this file" error because no standard OS tool claims ownership. For styling files, manual editing in a text editor is error-prone due to complex XML schemas; they are best handled by the proprietary App Stylist. However, for quick inspection, auditing, or documentation, converting these files to generic text formats is the most pragmatic workflow. For archiving or sharing code snippets without specialized software, convert your .isl to XML (for syntax highlighting), TXT (for raw viewing), or PDF (for non-editable documentation).
Convert.Guru analyzes your ISL file, detects the exact format, and lets you read the text inside.

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 ISL converter.
