Why do you want to do this? Storing sampled data, which are usually
binary data (commonly 12 or 16bit integers, depending on the hardware
used for sampling) consume much less space on your harddisk.

If you have the information how the data-format of Spike2 looks like it
should be easy to write a program which converts the data from every 
sampling device. Most of the software I know write the data as integers
to the disk. Mostly in a way like Point1 Channel1; point1 Channel2; point2 
channel1 and so on. Somewhat more difficult is the interprtation of the 
header where informations on sampling rates etc are stored. But this 
iformation is often provided from the vendor (programmer).

For mostly commercial software look at:

there is a huge number of useful links concerning software used in
neuroscience.

Hope this helps
