Thanks for the pointer. I've copied this script into our git at 
  ./util/obfuscate.pl
The script manages to process my 50MB file in approx. 30 seconds. The account 
and txn texts are all nicely obfuscated. 

The script also contains a random obfuscation for the amounts, which will 
simply cause lots of transactions to the equity account upon loading, but this 
could be enabled as well.

In a real data file there are still more places with text that need to be 
modified, e.g. the scheduled transaction templates, bayes import matching, and 
such. Also, the dates are left unmodified which may or may not be a problem. 

Anyone please feel free to check with this script and add more obfuscation 
steps. I would like to achieve a state where the script will obfuscate my 
personal data file enough so that I feel I can make it available as a test 
file.

Usage of the script: Save your normal file in uncompressed form to XML file. 
Then,

   ./obfuscate.pl  inputfile.gnucash > outputfile.gnucash

(Contrary to the comments, the output is just written to stdout, not in-place 
into the file.)

Thanks for the idea here!

Regards,
Christian
