What is an XSL file?
An .XSL file is an XML Stylesheet. The W3C developed this format to define how to display or transform .XML data. For example, it tells a browser how to convert raw .XML code into readable .HTML web pages. While most .XSL files contain plain text code, a rare alternative use for the .XSL extension is a CAD smart part symbol file used by Nemetschek Allplan. In the CAD scenario, the file is actually a ZIP archive.
How to open XSL files?
Because standard .XSL files contain plain text data, you can open them with any code editor. Developers often use tools like Visual Studio Code or Notepad++ to write and edit them. Web browsers like Google Chrome and Mozilla Firefox can process these files automatically when loading an associated .XML document. Additionally, spreadsheet software like Microsoft Excel uses .XSL files to properly import and format external data.
File inspection and conversion
If you have an unknown .XSL file, viewer.online/xsl analyzes .XSL files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you need to convert your data, you can transform the associated .XML information into accessible formats like .CSV or .JSON using convert.guru.
Summary
Because .XSL files use the known XML format, viewer.online/xsl can safely open and display them online, eliminating compatibility problems.
