Guitar Pro 4 and older tablature workflows require GP4 files, while scores downloaded from notation programs often arrive as compressed MusicXML (MXL). Convert the score when a collaborator or a legacy editor cannot open MXL.
What the MXL format is
MXL is the compressed form of MusicXML, an interchange format for sheet music. MuseScore, Finale, Sibelius, and Dorico can create or export MusicXML files; MXL is commonly used to share notated scores between different notation applications.
What the GP4 format is
GP4 is Guitar Pro 4’s native tablature and score format. It stores guitar or bass tracks, notation, tablature, rhythms, and playback information, and is useful when a recipient or older Guitar Pro installation specifically requires GP4.

Offline with desktop software
TuxGuitar is a free option for Windows, macOS, and Linux. Use a build with MusicXML import support, choose File → Import → MusicXML, select the MXL file, then choose File → Save As and select Guitar Pro 4 (.gp4) as the format.
Guitar Pro is the commercial option. Choose File → Import → MusicXML, open the MXL file, then use File → Save As and select GP4 as the output format. Menu labels can differ by version.
Quality and compatibility
MusicXML can describe standard notation without specifying guitar fingering. If the source lacks tablature, the application may choose playable string and fret positions automatically; check tuning, string assignments, and fingering before sharing. Review tuplets, repeats, articulations, and multi-voice passages after conversion because older GP4 files may not represent every MusicXML feature in the same way.
