Horizontal to vertical

Hi,
Silly question, if I have an excel file that looks something like this:

 
................. Subject 1 Subject 2 Subject 3 Subject 4
Fever..............13...........9.............23..........14
Headache.........2............12...........18..........23
Bleeding...........21...........45...........56.........88
Trauma............11...........23...........78.........22

But I need the information in columns rather than row:

 
................. Fever Headache Bleeding Trauma
Subject 1.......13.........2...........21........11
Subject 2........9.........12..........45........23
Subject 3.......23.........18.........56.........78
Subject 4.......14.........23.........88.........22


I know is a silly question but I need an AWK or perl script. I just do not know how to accomplish it.
Any help will be very much appreciated!

Not a silly question, just a common one. The trouble is, rotating the data usually means storing it entire in memory first since seeking in a text file is difficult.

You don't have to space things with endless numbers of .'s, you can put things in code tags [ code ] stuff [ /code ] and it'll space naturally in a fixed-width font.

I rearranged your data a little, to look like this:
Code:
.               Subject1        Subject2        Subject3        Subject4
Fever           13              9               23              14
Headache        2               12              18              23
Bleeding        21              45              56              88
Trauma          11              23              78              22

The . is there just to let awk know there's anything at all there -- otherwise it'd ignore that blank spot as pure whitespace. And the spaces in the titles have to go if your data's space-separated, since it'd take the header line as twice as many fields as it should.

Code:
$ cat rotate.awk
#!/usr/bin/awk -f
{
        # Record the maximum number of fields for later
        if(MAX<NF)      MAX=NF;
        # Save each line in DATA.  Line (record) 1 goes into DATA[1], etc.
        DATA[NR]=$0;
}

END {
        # Loop through each field
        for(N=1; N<=MAX; N++)
        {
                # Loop through each line, getting record N from line M in turn.
                PREFIX=""       ;       LINE=""
                for(M=1; M<=NR; M++)
                {
                        split(DATA[M], A, FS);
                        # Put the data records into one new line.
                        LINE=LINE PREFIX A[N];
                        PREFIX="\t";
                }
                # Print the line.
                print LINE;
        }
}

$ ./rotate.awk < data
.       Fever   Headache        Bleeding        Trauma
Subject1        13      2       21      11
Subject2        9       12      45      23
Subject3        23      18      56      78
Subject4        14      23      88      22
$

# 3  
nawk -f transpose.awk OFS='\t' myFile.txt
transpose.awk:
Code:
{for(i=1;i<=NF;i++){a[i,NR]=$i};m=NF;n=NR}
END {
   for(j=1;j<=m;j++)
         for(k=1;k<=n;k++)
           printf("%s%s",a[j,k], (k==n) ? ORS : OFS)
}
