Hello,

I just made this formula and thought it could save someone in the future some time.  Entering this into a formula field will give you the full state name based on abbreviation, just do a simple find and replace for "Field" in excel to edit the formula for your specific need.

if(Field='AL','Alabama',if(Field='AK','Alaska',if(Field='AZ','Arizona',if(Field='AR','Arkansas',if(Field='CA','California',if(Field='CO','Colorado',if(Field='CT','Connecticut',if(Field='DE','Delaware',if(Field='FL','Florida',if(Field='GA','Georgia',if(Field='HI','Hawaii',if(Field='ID','Idaho',if(Field='IL','Illinois',if(Field='IN','Indiana',if(Field='IA','Iowa',if(Field='KS','Kansas',if(Field='KY','Kentucky',if(Field='LA','Louisiana',if(Field='ME','Maine',if(Field='MD','Maryland',if(Field='MA','Massachusetts',if(Field='MI','Michigan',if(Field='MN','Minnesota',if(Field='MS','Mississippi',if(Field='MO','Missouri',if(Field='MT','Montana',if(Field='NE','Nebraska',if(Field='NV','Nevada',if(Field='NH','New Hampshire',if(Field='NJ','New Jersey',if(Field='NM','New Mexico',if(Field='NY','New York',if(Field='NC','North Carolina',if(Field='ND','North Dakota',if(Field='OH','Ohio',if(Field='OK','Oklahoma',if(Field='OR','Oregon',if(Field='PA','Pennsylvania',if(Field='RI','Rhode Island',if(Field='SC','South Carolina',if(Field='SD','South Dakota',if(Field='TN','Tennessee',if(Field='TX','Texas',if(Field='UT','Utah',if(Field='VT','Vermont',if(Field='VA','Virginia',if(Field='WA','Washington',if(Field='WV','West Virginia',if(Field='WI','Wisconsin',if(Field='WY','Wyoming','Other'))))))))))))))))))))))))))))))))))))))))))))))))))
