Magic / Types Ideas for making comma separated values easier to read and write Use text patterns (regular expressions/regex) to auto detect types Year [0-9]{4} e.g. 1982, 2014 etc. => assume year State / Region [A-Z]{1,2} e.g. T, ST, AZ etc. => assume state/region abbreviation Use (type) markers to auto detect types (e.g. km2, %, $ etc.)
