Have a look at the untab function:

 DESCRIPTION
 This function may be used either to convert tabs to spaces or, if called
 with a prefix argument, it will perform the opposite conversion from
 spaces to tabs.  This function operates on a region.

The "bufutils" mode in jedmodes.sf.net (in Debian part of the jed-extra
package) has also a untab_buffer functions that just does

public define untab_buffer ()
{
   push_spot();
   mark_buffer();
   untab ();
   pop_spot();
}
