Text to Numbers
Just because a value looks like an number to human doesn’t mean that Airtable thinks the value is a number.
In Airtable, text is left aligned and numbers are right aligned.
Converting text to a number with VALUE()
Sometimes when doing math, Airtable will convert text that looks like an number into a number for you. However, it is better to explicitly convert the
You can use VALUE() to convert text to a number. But watch out, because VALUE() sometimes looks at the surrounding text when converting a number, which can give unexpected results.
When possible, I recommend redesigning your base so that you can store the number in a number field instead of a text field.
Converting a Single Select to a Number
Because a single select field has a limited number of choices, it is easy to convert each text based choice to a number.
SWITCH( {Size},
"small", 1,
"medium", 2,
"large", 3

IF(
{Size},
VALUE(
REGEX_EXTRACT(
{Size},
"\\d+$"
)
)
)
