Free online MGU to MUSICXML converter

Band-in-a-Box saves songs as MGU files, but notation editors and score-sharing workflows often need MusicXML instead. Exporting to MusicXML makes the score available to compatible notation software without requiring the recipient to open the original Band-in-a-Box project.

What the MGU format is

MGU is a Band-in-a-Box song-file format, commonly used for songs containing a melody. It can store song information such as chord changes, melody, lyrics, tempo, and style settings. You may receive one when someone shares a Band-in-a-Box composition or find one in a project archive.

What the MUSICXML format is

MusicXML is a notation-exchange format used to move scores between music notation programs. It can represent written parts, notes, rhythms, and other score information; unlike an audio file, it is intended for editing and displaying notation.

How to convert MGU to MUSICXML

Online on 101convert.com

1. Upload the MGU file to the converter on this page.
2. Choose MusicXML as the output format and start the conversion. The conversion runs on our server with MuseScore.
3. Download the resulting file. You can submit several files as a batch; the per-file size limit is shown on the page.

Offline with desktop software

Band-in-a-Box is the direct desktop option and runs on Windows and macOS. Open the MGU file, then choose File → Save Special → Save as MusicXML. Save the exported MusicXML file and open it in a compatible notation editor if you need to inspect or edit the score. MuseScore does not natively open MGU files, so it cannot replace Band-in-a-Box for this direct export.

Quality and compatibility

MusicXML transfers notation rather than Band-in-a-Box’s complete playback setup. Style-based accompaniment and other program-specific behavior may not carry over as an equivalent editable arrangement. Check the exported score for correct parts, chord symbols, lyrics, and repeats before sharing or printing.
