Convert your DJ collection file between Rekordbox XML, Traktor NML and VirtualDJ database.xml: playlists and nested folders, hot cues, loops, beatgrid, BPM, musical key, duration and audio paths. The whole conversion runs in your browser, so the file is never uploaded to a server.
Every source file is parsed into a single normalised intermediate library — tracks, cues and playlists — and the target format is generated from it, so Rekordbox XML, Traktor NML and VirtualDJ database.xml convert both ways without a hand-built matrix of pairwise converters.
The playlist tree travels as folders and lists: both the Rekordbox ROOT node and the Traktor $ROOT/SUBNODES structure are read and written, keeping the order of the tracks inside every playlist.
Cue points are normalised to absolute seconds with their slot, label and length, so hot cues and loops survive the change of format; loop length is recomputed as end minus start whenever the target asks for it.
Title, artist, album, genre, musical key, BPM and duration are written to all three targets, and every track keeps its original audio location using the path convention that format expects.
Real migrations between DJ software without rebuilding your preparation by hand.
Export your Traktor collection as Rekordbox XML so playlists, hot cues, loops and beatgrid are ready for USB and CDJ export without marking anything again.
Load a Rekordbox XML into Traktor Pro as a collection.nml, keeping the folder structure and up to 8 hot cues per track, the limit of the format itself.
Convert VirtualDJ’s database.xml to Rekordbox XML keeping tags, BPM, key and cues, or the other way round for the tracks you play in VDJ.
The converter sums up tracks, playlists and folders, cue points and grid markers found in the source file, so you spot a truncated export before touching your main library.
The three formats that are read and written, with the exact schema the converter generates.
Pioneer DJ / AlphaTheta: read and written as a DJ_PLAYLISTS Version 1.0.0 document, the format Rekordbox software and USB export use.
Native Instruments: read and written as an NML Version 19 document, the structure Traktor Pro saves its collection in.
Atomix Productions: read and written as a VirtualDJ_Database document holding the track collection, tags, BPM and cues.
The conversion happens on the file you load: the tool never connects to Rekordbox, Traktor or VirtualDJ and never opens your audio files.
