When you build a system based on people, at a certain time, you need to fill your system with data for mass testing.
If you need hundreds (or thousands) of people, finding names can be a painfull moment to go through.
Here is a spreadsheet that generates as much names as you want.
It comes with 1000 random names (English) and each time you change something in the list, it refreshes itself with new names.
With your favorite spreadsheet editor, you can then generate, for instance, a JSON dataset, emails,… simply by using basic formulas.
