Most people in the community who work in string function improvements  
tend to use (and improve wherever it is lacking)  
benchtests/scripts/compare_strings.py for their result analysis.  Adding  
a flag to dump csv to that script ought to be trivial if that's what you  
need.

The script is under-documented though, so perhaps a wiki page describing  
what the script does and various example uses would go a very long way.

The reason for emitting json is precisely to allow developers to  
implement their own analysis tools around them when their use cases are  
niche.  Your specific use case is not niche and could be added as a flag  
to compare_strings.py if needed.  You only need a new flag --csv (or -o  
csv, tab, etc.) to print in csv instead of the current output, which is  
meant for reading on the terminal.
