Source format: GP4

GP4 is a guitar tablature file format associated with Guitar Pro 4, a popular music notation and tablature editor used by guitarists, bassists, and other musicians. GP4 files typically store tabs, standard notation, rhythms, effects, and playback data for a song arrangement. They are commonly used for sharing practice material, transcriptions, and band arrangements in a compact, editable form.

Target format: MXL

MXL is the compressed version of MusicXML, a widely supported standard for exchanging digital sheet music between notation programs. It is used by music notation software such as Finale, Sibelius, MuseScore, Dorico, and others. Compared with proprietary tab formats, MXL offers better interoperability, making it useful for editing, archiving, printing, and importing into different notation applications.

How to perform the conversion

The most reliable way to convert GP4 to MXL is to open the file in a program that can read Guitar Pro 4 and export to MusicXML. Guitar Pro itself is usually the best option if you have access to it.

  1. Open the .gp4 file in Guitar Pro.
  2. Check that the score plays correctly and that instruments, tuning, and notation are interpreted as expected.
  3. Choose File → Export or File → Export → MusicXML depending on the version.
  4. Select MusicXML compressed or MXL as the output format.
  5. Save the exported file with the .mxl extension.

If your notation software can open GP4 directly, you can also use it as an intermediate step:

  1. Import the .gp4 file into a compatible editor such as MuseScore or Guitar Pro.
  2. Review the imported score for layout or playback issues.
  3. Export using File → Export and choose MusicXML compressed or MXL.

You can also convert the file on 101convert.com for free, without installing any software, if that option is available for your file.

Notes on quality, compatibility, or limitations

GP4 to MXL conversion is not always perfect because Guitar Pro tablature can contain features that do not map cleanly to MusicXML. Common issues include guitar-specific effects, bends, slides, harmonics, palm muting, and some playback articulations. Layout may also change because MusicXML focuses on notation exchange rather than preserving the exact appearance of the original Guitar Pro score.

For best results, verify the exported file in a MusicXML-compatible editor after conversion. If the score contains many tab-specific techniques, expect some manual cleanup. Also note that MXL is compressed MusicXML, so it is ideal for exchange and storage, but some older software may prefer uncompressed .musicxml or .xml files instead.
