In the past I have substracted Month only string (JAN) from Jan-14 and then recoded individual months to new label (JAN) = (Q1). However this tack is very manual, is there a formula i can embed to automate this in the future?
If you have JMP16 you could first convert the character column to date column with format pattern and then use Quarter function
Names Default To Here(1);
dt = Current Data Table();
Column(dt, 1) << Set Name("MonthYear");
Column(dt, 1) << Data Type(Numeric,
Format("Format Pattern", "<MMM><-><YY>", 35),
Input Format("Format Pattern", "<MMM><-><YY>")
);
dt << New Column("Q", Numeric, Ordinal, Formula(Quarter(:MonthYear)));</YY></MMM></YY></MMM>If you don't have JMP16 you could do "conversion list" of months and then use that instead to get Quarters
Edit:
Formula for JMPs before 16 and no conversion to first column using list of months, contains(), word() and ceiling()
dt << New Column("Q",
Numeric,
Ordinal,
Formula(
Local({month_list = (month_list = {"JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP", "OCT", "NOV", "DEC"})},
Ceiling(Contains(month_list, Word(1, :MonthYear, "-")) / 3)
)
)
);Appreciate the quick response - I'm on JMP 14 so do not have format pattern. I have added a sample file, could you perhaps show me how to use conversion list?
Thanks!

Attempted to apply but perhaps i have input formula with basic error?
