pyside6-linguist is a tool that wraps Qt Linguist, Qt’s tool to translate user interfaces and manage application localizations. It supports Qt’s own TS file format as well as the XML Localization Interchange File Format (XLIFF). There are no differences between the version bundled with PySide and the one from Qt.

For more information on how to use this tool, read Qt’s documentation here: Qt Linguist. Read more about how to translate PySide applications here: Translating Applications.
