Reverse an xxd hexdump Given an xxd hexdump such as this one:
00000000: 1f8b 0808 4920 2258 0003 7069 6c6c 6f77  ....I &quot;X..pillow
00000010: 2e74 7874 00d3 d707 8218 10d0 2799 c545  .txt........'..E
00000020: ba96 41a1 994c 7d60 d650 d53c 44a3 8a22  ..A..L}`.P.&lt;D..&quot;
00000030: cd43 34aa 28d2 3c44 a38a 22cd 4334 aa28  .C4.(.&lt;D..&quot;.C4.(
00000040: d20c 00fd 512d 46b8 0500 00              ....Q-F....

Reverse it to produce the original input:
I &quot;Xpillow.txt����'��E��A��L}`�P�&lt;D��&quot;�C4�(�&lt;D��&quot;�C4�(�
                                                      �Q-F�

(This is only an approximation of the original input)
You do not need to expand to shellcodes.
Dupe alert
This is not a duplicate of the other xxd hexdump challenge because this one does not to be expanded to shellcodes.
Rules

You may not use external programs that parse hexdumps (such as xxd).
Standard loopholes apply
This is code-golf, smallest code wins.

Note that &lt;C-v&gt; represents the unprintable character 0x16.
Explanation
This answer is pretty fun because it's about modifying the input into V code and then executing that code. I'll explain each command one at a time
Î                &quot; On every line:
 dW              &quot;   Delete a word
   40|           &quot;   Move to the 40th column
      D          &quot;   Delete everything after this

Í                &quot; Remove all occurrences of
                 &quot; A space 
  üî             &quot; or a newline

Now the buffer looks like this:
1f8b080849202258000370696c6c6f772e74787400d3d707821810d02799c545ba9641a1994c7d60d650d53c44a38a22cd4334aa28d23c44a38a22cd4334aa28d20c00fd512d46b8050000

The command to insert a character by its hex value is
&lt;C-v&gt;x&lt;hex-value&gt;

Here is where we start transforming it into actual V code.
Ó                &quot; Replace
 ..              &quot;   Two characters
   /             &quot;   with
    &lt;C-v&gt;&lt;C-v&gt;x  &quot;   the text &quot;&lt;C-v&gt;x&quot;
               &amp; &quot;   And the two characters we just matched

&lt;C-v&gt;x1fi&lt;C-v&gt;x8bi&lt;C-v&gt;x08i&lt;C-v&gt;x08i&lt;C-v&gt;x49...

But the command has to be in insert mode. So we insert an 'i' at the beginning.
éi               &quot; Insert an 'i'
  D              &quot; Delete this line
   @&quot;            &quot; And evaluate it as V code
