fmp12 to csv conversion is typically searched by users that are exploring options how to export content of FileMaker Pro databases (in this case from version 12) to CSV format.
As far as we know, this is only doable with FileMaker Pro and no other software can help you out with this. If you do not have access to the software, you have to find someone who does and is willing to do the export for you. There is unfortunately no way around this.
