ConvertCSV2TXF is a stand-alone Java executable, so it should run on any platform. All you need is java loaded on your system, which is a free download from Sun Microsystems.
A free Trial version of the program can be obtained here. The trial version is the same as the full version, but is limited to converting just 2 transactions, just so you can see how it works. The full version will convert an unlimited number of transactions. Note - If you have any problems with the trial version, send me an email and I'll help you get it sorted out.
