Scores saved by NoteWorthy Composer may need to be opened in notation software that accepts MusicXML, or shared with collaborators who use that interchange format. Converting the score keeps it in editable notation form rather than turning it into audio.

What the NWC format is

NWC is the native score format of NoteWorthy Composer, a notation program for Windows. It stores musical notation and score elements for editing and playback; NWC files are commonly encountered in older scores created or shared by NoteWorthy Composer users.

What the MUSICXML format is

MusicXML is a notation interchange format supported by many score editors. It lets compatible programs import and edit a score without requiring the original application. Files commonly use the .musicxml or .xml extension; compressed MusicXML may use .mxl.

How to convert NWC to MUSICXML

Online on 101convert.com

Upload the NWC file on the converter page. Several files can be added for batch conversion; check the page for its per-file size limit.
Start the conversion to MusicXML.
Download the converted file or files.

The conversion runs on the site’s server with nwc2xml.

Offline with desktop software

Use the nwc2xml utility locally to convert the score without uploading it. Open the utility, provide the NWC input file, choose a MusicXML output file, and run the conversion. Follow the utility’s included instructions for its exact controls or command syntax; those can vary by distribution. Open the result in a MusicXML-compatible notation editor to check it.

Quality and compatibility

MusicXML carries notation, not a rendered page image, so the receiving program may reflow measures and change spacing or page layout. Check the imported score for tuplets, lyrics, dynamics, repeats, and NWC-specific objects, since unsupported or differently interpreted elements may not transfer exactly.
