You can use the following formula to convert state abbreviations to full state names in Excel:
=SWITCH(A2, "AL", "Alabama", "AK", "Alaska", "AZ", "Arizona", "AR", "Arkansas", "CA", "California", "CO", "Colorado", "CT", "Connecticut", "DE", "Delaware", "FL", "Florida", "GA", "Georgia", "HI", "Hawaii", "ID", "Idaho", "IL", "Illinois", "IN", "Indiana", "IA", "Iowa", "KS", "Kansas", "KY", "Kentucky", "LA", "Louisiana", "ME", "MAINE", "MD", "Maryland", "MA", "Massachusetts", "MI", "Michigan", "MN", "Minnesota", "MS", "Mississippi", "MO", "Missouri", "MT", "Montana", "NE", "Nebraska", "NV", "Nevada", "NH", "New Hampshire", "NJ", "New Jersey", "NM", "New Mexico", "NY", "New York", "NC", "North Carolina", "ND", "North Dakota", "OH", "Ohio", "OK", "Oklahoma", "OR", "Oregon", "PA", "Pennsylvania", "RI", "Rhode Island", "SC", "South Carolina", "SD", "South Dakota", "TN", "Tennessee", "TX", "Texas", "UT", "Utah", "VT", "Vermont", "VA", "Virginia", "WA", "Washington", "WV", "West Virginia", "WI", "Wisconsin", "WY", "Wyoming")
This particular formula converts the state abbreviation in cell A2 to a full state name.
The following example shows how to use this function in practice.
Example: Convert State Abbreviation to Full Name in Excel
Suppose we have the following list of state abbreviations in Excel:
Suppose we would like to display the full state name for each abbreviation in column B.
To do so, we can type the following formula into cell B2:
=SWITCH(A2, "AL", "Alabama", "AK", "Alaska", "AZ", "Arizona", "AR", "Arkansas", "CA", "California", "CO", "Colorado", "CT", "Connecticut", "DE", "Delaware", "FL", "Florida", "GA", "Georgia", "HI", "Hawaii", "ID", "Idaho", "IL", "Illinois", "IN", "Indiana", "IA", "Iowa", "KS", "Kansas", "KY", "Kentucky", "LA", "Louisiana", "ME", "MAINE", "MD", "Maryland", "MA", "Massachusetts", "MI", "Michigan", "MN", "Minnesota", "MS", "Mississippi", "MO", "Missouri", "MT", "Montana", "NE", "Nebraska", "NV", "Nevada", "NH", "New Hampshire", "NJ", "New Jersey", "NM", "New Mexico", "NY", "New York", "NC", "North Carolina", "ND", "North Dakota", "OH", "Ohio", "OK", "Oklahoma", "OR", "Oregon", "PA", "Pennsylvania", "RI", "Rhode Island", "SC", "South Carolina", "SD", "South Dakota", "TN", "Tennessee", "TX", "Texas", "UT", "Utah", "VT", "Vermont", "VA", "Virginia", "WA", "Washington", "WV", "West Virginia", "WI", "Wisconsin", "WY", "Wyoming")
We can then click and drag this formula down to each remaining cell in column B:
Column B now displays the full state name for each state abbreviation in column A.
How This Formula Works
Recall the formula that we used to display the full state name for the state abbreviation:
=SWITCH(A2, "AL", "Alabama", "AK", "Alaska", "AZ", "Arizona", "AR", "Arkansas", "CA", "California", "CO", "Colorado", "CT", "Connecticut", "DE", "Delaware", "FL", "Florida", "GA", "Georgia", "HI", "Hawaii", "ID", "Idaho", "IL", "Illinois", "IN", "Indiana", "IA", "Iowa", "KS", "Kansas", "KY", "Kentucky", "LA", "Louisiana", "ME", "MAINE", "MD", "Maryland", "MA", "Massachusetts", "MI", "Michigan", "MN", "Minnesota", "MS", "Mississippi", "MO", "Missouri", "MT", "Montana", "NE", "Nebraska", "NV", "Nevada", "NH", "New Hampshire", "NJ", "New Jersey", "NM", "New Mexico", "NY", "New York", "NC", "North Carolina", "ND", "North Dakota", "OH", "Ohio", "OK", "Oklahoma", "OR", "Oregon", "PA", "Pennsylvania", "RI", "Rhode Island", "SC", "South Carolina", "SD", "South Dakota", "TN", "Tennessee", "TX", "Texas", "UT", "Utah", "VT", "Vermont", "VA", "Virginia", "WA", "Washington", "WV", "West Virginia", "WI", "Wisconsin", "WY", "Wyoming")
This formula uses the SWITCH function, which uses the following basic syntax:
SWITCH(value to switch, find1, return1, find2, return2, ...)
In our particular formula, we analyze cell A2 and do the following:
- Look for “AL” – if found then return Alabama
- If not found, then look for “AK” – if found then return Alaska
- If not found, then look for “AZ” – if found then return Arizona
And so on.
By using this logic, we’re able to return a full state name based on each state abbreviation.
