Is there a way to decipher code from a blueprint?

[Gordfact47]

I noticed when opening my blueprint files a series of letters and numbers I guess this translates into the book when you import string.

Does the computer make the number/letter jumble or is this done by hand?

Here is an example of what I mean:

It's the serialized representation of the blueprint. I'm not sure what you mean by "by hand".

See Blueprint string format.

Oh its compressed data with zlib deflate

there are some decoders around like this one:
