Free online CAP to MXL converter

A notation program or collaborator may require MusicXML rather than a Capella score file to open and edit the music. Converting a CAP score to MXL packages the notation in a format supported by many music-notation applications.

What the CAP format is

In music composition, CAP is a native score format used by the Capella notation program. It stores musical notation for editing and playback, and is commonly encountered in scores created with Capella or shared by its users.

What the MXL format is

MXL is compressed MusicXML: a smaller, packaged form of MusicXML used to exchange editable notation between score applications. It is useful when the recipient’s program does not read CAP files but supports MusicXML.

How to convert CAP to MXL

Online on 101convert.com

1. Upload the CAP file on the converter page. You can add several files for batch conversion; the page shows the per-file size limit.
2. Choose MXL as the output format if prompted, then start the conversion. The conversion runs on the site’s server using MuseScore.
3. Download the resulting MXL file.

Offline with desktop software

MuseScore is free, open-source notation software for Windows, macOS, and Linux. Open the CAP file with File → Open, then use File → Export and select Compressed MusicXML (*.mxl) as the format. If the CAP file does not open, that MuseScore version may not support its particular CAP variant.

Quality and compatibility

MXL contains notation data, not an audio rendering. Because CAP and MusicXML represent scores differently, inspect the exported file in its destination application, especially page layout, articulations, and notation elements specific to Capella.
