A formula is an expression made from values, field references, functions, and operators.

Formula envelopes

Use a ${...} envelope when a formula is embedded in calculated text:
A field that expects only an expression can also accept the expression without the envelope:
Use ={...} for a nested sub-expression in places that require the explicit subformula form:

Call a function

Write the function name, then place its inputs inside parentheses:
Separate multiple inputs with commas:
Function names are case-sensitive. Write Len(...), not len(...).

Nest functions

The result of one function can be passed into another:
If and Case evaluate only the branch that is selected. This is useful when an unused branch would require data that may not exist.

Write literal values

Escape \n, \r, \t, \\, \', or \" inside text when needed.

Add a comment

// starts a comment that continues to the end of the line:

Next step

Connect the expression to form data with values and references, then use the formula index to choose a function.
