Extract text from WiX XML patch files (WIXMSP)
To convert WIXMSP patch files to another format, you need WiX Toolset or other Developer software.
To convert other file formats to the "Intermediate XML Build File" file type, you need software like WiX Toolset or a similar tool.
A .wixmsp file is an intermediate XML document used by the WiX Toolset to define a Windows Installer Patch. Developers use the WiX build environment to write XML code that determines how Windows software is installed and updated. During the patch creation process, the WiX compiler processes these source files to generate a .wixmsp file. This file acts as a structured manifest detailing the specific patching instructions before they are compiled into a final binary patch.
The major disadvantage of a .wixmsp file is that it is strictly an intermediate developer file. You cannot double-click it to install a software update because it does not contain the actual compiled binaries or file diffs. It requires the complete WiX Toolset, specifically the pyro.exe linking tool, alongside the original wixpdb database and wixmst transform files to generate a working MSP installer. Because of this complex dependency chain, standard online converters cannot simply turn a .wixmsp file into an executable MSP patch.
If you just need to inspect the code, your best option is to convert the .wixmsp file to standard XML or TXT.
Convert.Guru analyzes your WIXMSP file, detects the exact format, and lets you read the text inside.
If you want to convert WIXMSP file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use WiX Toolset or similar software from the "Software Installation Patching" 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 WIXMSP, try WiX Toolset or another comparable tool in the "Software Installation Patching" 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 WIXMSP converter.
