Software that can be used for conversion of spb file type to text format.
The only way how some kind of SPB to text conversion would work, is to convert SPB to VCF using Samsung Kies. VCF is basically a specially formatted text file, so you can view it using any text editor.
If you are looking for a way to extract messages out of SPB backups, these may also be probably exported using Samsung Kies.
Unfortunately, there is no detailed software record in the database for this conversion.
