Is there a way to convert .spbm files directly to .csv format.
Converting Samsung Contact Backup files directly to Comma-Separated Values Files (.spbm to .csv conversion), most likely, relates to users attempting to recover contacts data from their backups generated by Samsung Smart Switch.
It is, unfortunately, not possible to directly convert or extract .spbm to .csv. You could, however, recover the backup data using the actual Smart Switch tool, and simply export your contacts data.
