ThoughtSpot allows you to create derived columns in worksheets using formulas. You create these columns by building formulas using the Formula Assistant. An individual formula is constructed from n combination of operators and functions.

This reference lists the various operators and functions you can use to create formulas.

## Operators

Operator Description Examples
`and` Returns true when both conditions are true, otherwise returns false. `(1 = 1) and (3 > 2) = true`
`lastname = 'smith' and state ='texas'`
`if…then…else` Conditional operator. `if (3 > 2) then 'bigger' else 'not bigger'`
`if (cost > 500) then 'flag' else 'approve'`
`ifnull` Returns the first value if it is not null, otherwise returns the second. `ifnull (cost, 'unknown')`
`isnull` Returns true if the value is null. `isnull (phone)`
`not` Returns true if the condition is false, otherwise returns false. `not (3 > 2) = false`
`not (state = 'texas')`
`or` Returns true when either condition is true, otherwise returns false. `(1 = 5) or (3 > 2) = true`
`state = 'california' or state ='oregon'`

## Aggregate functions
