Extract text from GMB files
To convert your GMB file to another format, you need Google Translator Toolkit or other Developer software.
To convert other file formats to the "Localization Archive" file type, you need software like Google Translator Toolkit or a similar tool.
The .GMB file extension is most notoriously associated with the Google Message Bundle, a legacy container format used by the now-defunct Google Translator Toolkit. These files were essentially ZIP archives packaging source documents (like HTML or DOC) alongside translation memory data for localization projects. Since Google shut down the Toolkit in late 2019, users holding these files often find themselves locked out of their translation history, unable to open them in modern Computer-Assisted Translation (CAT) tools like Trados Studio or MemoQ without manual intervention.
A secondary, distinct use of the format is as a Grafcet Sequential Function Chart created by MHJ-Software for industrial automation logic. These are specialized engineering schematics used to visualize PLC programming sequences. The proprietary nature of MHJ's software means you cannot view these logic charts in standard image viewers or web browsers, making sharing technical documentation difficult without conversion.
To reclaim data from a Google .GMB archive, the most pragmatic solution is to rename the extension to ZIP and extract the contents to locate standard TMX (Translation Memory eXchange) or XML files inside. For broader compatibility, converting extracted data to CSV or XLIFF is recommended for importing into current translation management systems. For Grafcet .GMB files, the goal is typically documentation or archiving; converting these technical charts to PDF or vector formats like SVG ensures the logic diagrams remain viewable to engineers who don't have the specific simulation software installed.
Convert.Guru analyzes your GMB file, detects the exact format, and lets you read the text inside.
Users also converted BUN, GVI and BBQ files.
If you want to convert GMB file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use Google Translator Toolkit or similar software from the "Localization Data Container" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to GMB, try Google Translator Toolkit or another comparable tool in the "Localization Data Container" 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 GMB converter.
