Airtable Formula to Convert SSN Numbers to Letters Using Reverse Alphabet Mapping

Yeah there are a couple different ways to handle this. The easiest (since I’m not a Regex expert) is using a nested Substitution formula. Try this…

SUBSTITUTE(
    SUBSTITUTE(
    SUBSTITUTE(
    SUBSTITUTE(
    SUBSTITUTE(
    SUBSTITUTE(
    SUBSTITUTE(
    SUBSTITUTE(
    SUBSTITUTE(
        SUBSTITUTE(
        ssn,
        '2','b'),
        '1', 'c'),
        '3', 'd'),
        '4', 'e'),
        '5', 'f'),
        '6', 'g'),
        '7', 'h'),
        '8', 'i'),
        '9', 'j'),
        '0', 'k')

Replacing the ssn field with whatever your field is titled. You can also pick the letter each number is meant to represent. The only thing here is it handles each digit individually, so 26 is “bg” not “a”. If you want to replace across the whole alphabet then I think you’d need a Regex formula that someone else might be able to drop in.

Airtable doesn’t have very robust formulas. You could probably use a REGEX formula to do it, but outside of that, you would need to nest multiple SUBSTITUTE() functions like this:

SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
{Your Social Security Number Field},
"1", "Z"
),
"2", "Y"
),
"3", "X"
),
"4", "W"
),
"5", "V"
),
"6", "U"
),
"7", "T"
),
"8", "S"
),
"9", "R"
),
"0", "Q"
)

Hope this helps!
