OnSong can import plain text files just as it would OnSong or ChordPro files. In fact, all of these files are treated as the text-based chord chart and editable in the Song Editor. This means that you can write your songs with a
.txt file extension and OnSong will recognize the file as either:
The OnSong file format is the native text-based chord chart format of OnSong that uses simple text and human-readable syntax to create chord charts.
The ChordPro file format is used by other applications and has a syntax similar to the OnSong file format. Instead of using reader-friendly syntax, it uses curly braces to define "tags". These tags provide information about the song structure.
