MusicXML ↔ NoteWorthy converter

convert your music files

Requirements | Terms and cost | Use it! | Version History

This online converter will (try to) read most MusicXML files and create an approximate representation of the score in NoteWorthy Composer v2.5 text format, or read a NWC text file and create a MusicXML file with it. Yes, it now works both ways! more...

To begin the conversion process, use the button below. Current version information is MusicXML2NWC v2.3.5.

Since February 6, 2013, over 11300 input files were successfully converted. more...

Tip #1: To save time and get a more coherent result when converting scanned music (xml => nwctxt), try to merge all pages of the musical piece in a single MusicXML file instead of submitting pages one by one. SharpEye, Photoscore and most other music scanning software have options to merge pages.

Tip #2: Sometimes, MXL files are incorrectly named .xml. The current version of the converter will not be able to detect it and will fail on invalid XML. If it fails, maybe you should try renaming it to .mxl and try again.

Tip #3: Binary NWC files cannot be converted here. Please use Noteworthy Composer v2.5 and up to save the file as "NWC Text file" (.nwctxt).

Tip #4: Long pieces with several parts, for instance the director's score of the 5th symphony, may fail to convert because of memory limitation. If possible, split the part in pieces and try again.

Version History

Version 2.3.5

  • Improved MusicXML 3.0 compatibility, validated DTD ordering of output files. Compatibility with MuseScore 2.0.

Version 2.3.4

  • Fixed: (nwc2xml) Title (movement-title) element is inserted at the wrong location in the XML structure
  • New: (nwc2xml) Tempo element is now supported

Version 2.3.3a

  • Fixed: (xml2nwc) Conversion fails with most xml files

Version 2.3.3

  • New: (xml2nwc) Better detection of incorrect Forward/Backup values that can (arguably rightfully) cause the converter to fail
  • New: (xml2nwc) Better tolerance on incorrect encoding of XML files
  • New: Better pre-detection of invalid files (pdf renamed as xml or mxl, non-MusicXML XML files, etc)
  • Fixed: (nwc2xml) NWC files without midi instrument set may fail to import

Version 2.3.2a

  • Fixed: (nwc2xml) Exception when processing Direction elements

Version 2.3.2

  • Fixed: (nwc2xml) 2-voices NWC chords can insert unwanted offsets in the XML score
  • Fixed: (nwc2xml) Some metadata tags don't respect the MusicXML DTD as the data is encapsulated in an extra value node.

Version 2.3.1

  • Disabled support for pitch/alter because of very limited usefulness and useless accidental alterations introduced. Proper support (when accidental tag is absent) would require full tonality state to be kept for each measure during conversion. We don't know any MusicXML software producing pitch-altered notes without inserting an accidental node.

Version 2.3

  • Fixed: (xml2nwc) On multi-staff parts, slurs and tie from one staff may be applied to other staves too.
  • Workaround: (xml2nwc) Sybelius-exported XML files may miss some <voice> information on some <note> tags. New code to try to figure out the correct voice.
  • (xml2nwc) Passed the whole Lilipond MusicXML test suite on the converter and fixed several small issues
  • Fixed: (xml2nwc) Flat-flat isn't converted
  • New: (xml2nwc) Support for "pitched" rests
  • New: (xml2nwc) Partial support for "Long" and "Breve" note types (converted to tied wholes)
  • New: (xml2nwc) Partial support non-traditional key signatures (but not double sharp or double flat)
  • New: (xml2nwc) Support for all noteheads supported by NWC
  • Fixed: (xml2nwc) Chords are often missing one or more notes.
  • New: (xml2nwc) Support for different lyrics on each staff of a multi-staff measure
  • New: (xml2nwc) Support for different key signature on each staff of a multi-staff measure
  • New: (xml2nwc) Support multi-measure rests

Version 2.2.3

  • New: (xml2nwc) When decoding XML files, if the file contains invalid/corrupted UTF-8 characters, the invalid characters are stripped and decoding is attempted again

Version 2.2.2

  • Added: (nwc2xml) more validity checks on nwctxt data
  • Fixed: a few lines didn't pass PHP 5.4 strict standards and issued warnings

Version 2.2.1

  • Added: (xml2nwc) Transposition support for MusicXML to nwctxt conversion. The reverse operation was already supported.
  • Various minor fixes

Version 2.2

  • Implemented converter from nwctxt to MusicXML
  • Fixed: (xml2nwc) Octave-shift on key is not handled correctly
  • Fixed: (xml2nwc) Extra spaces are added between lyrics syllable

  • Support for compressed MusicXML files (*.mxl)

Version 2.0.5

  • New: MusicXML part-name, part-name-display and part-name-abbreviation elements are handled respectively as "staff name", "staff label" and "abbreviated".

  • Server-side changes to (hopefully) help IE8 handle downloads

Version 2.0.3

  • Fixed: Beams are missing

Version 2.0.2

Version 2.0

  • Rewritten as a server-side code for online processing, no need to install anything anymore
  • No need for NWC to be open or installed on the machine where the converter is used
  • The converter now generates a full .nwctxt file that can be open in NWC 2.5+
  • The offline, .NET version is not maintained and will not be available anymore
  • Support for multiple lines of lyrics (thanks to Phil Holmes)

Version 1.12

  • Completely empty measures are filled with visible rests. Fixed a crash when the XML file just can't be read

Version 1.11

  • Manifest update for better Vista compatibility

Version 1.10

Version 1.09

  • Fixed a possible infinite loop while trying to find the correct rest value to fill an incomplete measure

  • New Replaced quarter, half and full invisible rests by no-head short-stems muted invisible notes - better look in NWC itself, no change when printing (thanks to Tina)
  • Fixed: Rest-filling problem for a very particular voice pattern. The problem was happening in the last measure of the Elite test file.

Version 1.0

  • Still a desktop program requiring the Microsoft .Net Framework
  • New: Voiced chords and separate voices are now translated properly, in separate layered staves.

Version 0.10

  • Fixed: Some precision is lost during rest duration calculation, resulting in incorrect rest values (double-dotted rests intead of full ones)

Version 0.9

  • Basic support for unpitched notes (automatic X notehead)

Version 0.8

  • Tested and adapted for Windows98. Added a File/Open dialog
