Problem of data format in Visual Analog

Hello

I'm trying to use the tool "Pattern Loader" to see how works the AD9257. When I load my file .txt, I got an error message telling "extra characters cannot be parsed are at the end of the string" (it's translated from french). It seems that the tool doesn't accept comma or point for decimal numbers, but is there a solution to use my datas ? I'd like to use that type : 

0.652
0.652
0.656

for about 25k datas.

Please tell me if there's a solution, and please excuse me for my probable mistakes in english.
Thanks you
