Finale scores saved as MUSX cannot be opened directly by many notation programs or archival workflows that accept MusicXML. Exporting to MusicXML makes the notation available for editing in compatible score software and for exchanging between applications.

What the MUSX format is

MUSX is Finale’s native score-document format, used for editable notation such as notes, parts, lyrics, and layout. Finale has created MUSX files since Finale 2014; you encounter them when receiving a Finale score or working with a Finale project.

What the MUSICXML format is

MusicXML is an interchange format for written music. Notation programs use it to share scores, parts, rhythms, lyrics, and many expressive markings. Uncompressed files commonly use .musicxml or .xml; compressed MusicXML files use .mxl. It is useful when moving a score between different notation applications, though it does not preserve every program-specific feature or layout detail.

Convert online on 101convert.com

Open the MUSX-to-MUSICXML converter on 101convert.com and upload the score file. Several files can be added as a batch; the page shows the per-file size limit.
Start the conversion and select or confirm MUSICXML as the output format if prompted. The conversion runs on the server with denigma.
Download the converted file or files and open them in a MusicXML-compatible notation program.

Convert offline with desktop software

Use Finale, the application that creates MUSX files. Open the score, then choose File → Export → MusicXML (the exact menu wording can vary by Finale version) and save the exported file. Finale is commercial software for Windows and macOS; existing installations can perform the export. MuseScore does not directly open MUSX, so export from Finale before importing the MusicXML into MuseScore or another notation program.

Quality and compatibility

Check the exported score for page layout, fonts, articulations, playback instructions, and Finale-specific markings: MusicXML transfers notation data, but applications may interpret unsupported features differently. Keep the original MUSX file if you may need to edit Finale-only details later.
