I have been using it forever (over 10 years) to organize financial data and do taxes. While I should credit Python because these are Python programs after all, it is really Leo that enables me to easily keep data organized. Queries can be ran by easily running Python scripts inside of Leo with results directed to the log panel, turning Leo into a light-weight IDE.

For example the top node for accounting is like this:

  #@killcolor
  # accounting

  from datetime import date
  import pprint
  import math

  <<defs>>

  year = 2006

  <<2006>>

  inc_year()
  <<2007>>

  inc_year()
  <<2008>>

  ... more data

  inc_year()
  <<2018>>

  inc_year(0) #update certain yearly balance records without 
  advancing

  def runacct(argv):
      if len(argv) > 1:
        if argv[1] == 'q':
            transquery(argv[2].upper())
        elif argv[1] == 'g':
            groupquery(argv[2].upper())
        elif argv[1] == 'h':
            holdingquery(argv[2].upper())
        elif argv[1] == 'm':
            if len(argv) == 3:
                monthquery(int(argv[2]))
            else:
                monthquery(int(argv[2]), int(argv[3]))
        elif ... many other query options
      else:
        balancequery()

  if __name__ == '__main__':
      from sys import argv
      runacct(argv)
