The >> is parsed in a special way. To allow people to use it without 
quoting the filename, the filename isn't evaluated but turned directly into 
a string. To avoid that behavior, you can use the FullForm of the same command.

ExportDatas[FileName_,DataToBeExport_] :=
Put[DataToBeExport, FileName]

DataToBeExport={{0,0},{5,4}};
ExportDatas["Spring.txt",DataToBeExport]

Or you could just use Export

Export["Spring.txt", DataToBeExport, "Expression"]
