Extract text from Apple localization files (LG)
To convert LG localization files to another format, you need Apple Xcode or other Developer software.
To convert other file formats to the "Localization Project File" file type, you need software like Apple Xcode or a similar tool.
The .lg file extension typically functions as an Apple Localization Project file. Developers use these XML-based archives to manage translation strings for iOS and macOS applications. Less frequently, .lg files store handwritten math expression graphs for CROHME academic competitions, knitting machine patterns for Logica LKS software, or serialized graph data for Python's LineGrapher tool.
You can open localization files natively using Apple Xcode. Math and serialized graph files usually require custom scripts in Python utilizing data libraries like NumPy.
.lg files suffer from severe compatibility limits. Apple localization archives are useless to freelance translators who use Windows or standard tools like SDL Trados. Knitting patterns require proprietary software costing hundreds of dollars. Without the exact target environment, these specialized files are completely inaccessible to standard users.
Converting your .lg file is the most pragmatic workaround. For app translations, convert to XML, XLIFF, or CSV so third-party translators can actually read and edit the text. For math expressions and graph data, convert to JSON or TXT to inspect the node structures securely.
Convert.Guru analyzes your LG file, detects the exact format, and lets you read the text inside.
Users also converted XMP, XCT, RECORD and CONTENTS files.
If you want to convert LG file to , you can use Apple Xcode or similar software from the "Software Localization Data" category. In the File menu, look for Save As… or Export….
To convert files to LG, try Apple Xcode or another comparable tool in the "Software Localization Data" 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 LG converter.
