Formulas

Adding formula column

1. Click on '+' (Add column)

2. Populate column Name

3. Select column Type as 'Formula'

4. Insert required formula

You can use explicit numerical values/ strings as needed, e.g. 123 (numeric) or "123" (string).
You can reference column names in equation with {}, e.g. {column_name}, if the column name conflicts with literals
Table below lists supported formula & associated syntax
Nested formula (formula equation referring to another formula column) is supported

5. Click on 'Save'

Editing formula column

Unlike other column types, formula cells cannot be modified by double-clicking since the value is generated based on the formula. Instead, the vaule can be changed by updating the formula in the column setting.

Logical operators, along with Numerical operators can be used to build conditional expressions.

Examples:

IF({marksSecured} > 80, "GradeA", "GradeB")

SWITCH({quarterNumber},

    2, 'Apr-Jun',
    3, 'Jul-Sep',
    4, 'Oct-Dec',
    'INVALID'
