Convert MST to XML

Understanding MST and XML file formats

MST files are Microsoft Transform files used primarily to customize Windows Installer packages (MSI files). They contain configuration changes, such as installation options or paths, and are commonly used by IT administrators to automate software deployments.

XML (eXtensible Markup Language) files are plain text files structured with tags to store and transport data. XML is widely used for data exchange between systems due to its readability and flexibility.

Why convert MST to XML?

Converting an MST file to XML can be useful for analyzing, editing, or documenting the customizations applied to an MSI package. XML format makes it easier to review and share the configuration details in a human-readable way.

How to convert MST to XML

There is no direct, one-click converter for MST to XML, but you can extract the data from an MST file and export it to XML using specialized tools. The process involves viewing the MST file's contents and saving or exporting the data in XML format.

Recommended software for MST to XML conversion

• InstEd: A free MSI/MST editor that allows you to open MST files, view their tables, and export data. To export to XML, open your MST file, then use File → Export Tables → XML.
• Orca: A Microsoft tool for editing MSI and MST files. While Orca does not export directly to XML, you can view the tables and manually copy data for XML conversion.
• Advanced Installer: A commercial tool with advanced export options, including XML export for project data.

Step-by-step conversion using InstEd

1. Download and install InstEd from the official website.
2. Open InstEd and load your MST file.
3. Go to File → Export Tables → XML.
4. Choose the destination folder and save the XML file.

This process will create an XML file containing the tables and data from your MST file, making it easier to review or share the configuration changes.

Conclusion

While MST and XML serve different purposes, converting MST to XML is possible using tools like InstEd. This allows for easier analysis and sharing of Windows Installer customizations.
