In crx.names from data folder, says : All attribute names and values have been changed to meaningless symbols to protect confidentiality of the data.

But they give you the values that they use:

Attribute Information:

A1:   b, a.
A2:   continuous.
A3:   continuous.
A4:   u, y, l, t.
A5:   g, p, gg.
A6:   c, d, cc, i, j, k, m, r, q, w, x, e, aa, ff.
A7:   v, h, bb, j, n, z, dd, ff, o.
A8:   continuous.
A9:   t, f.
A10:  t, f.
A11:  continuous.
A12:  t, f.
A13:  g, p, s.
A14:  continuous.
A15:  continuous.
A16: +,-         (class attribute)

You can give to this information, the meaning that you need.

For create this to arff file you write something like that:

%Test Data set

@relation Credit Approval Data Set 

@attribute attribute_name {a,b}
@attribute ...



@data
b,30.83,0,u,g,w,v,1.25,t,t,01,f,g,00202,0,+

Add the next attribute reading the credit.lisp, you need 16 attributes. Save the file how: name file.arff. You can create this file in a text editor of your preferred.
