Formula envelopes
Use a${...} envelope when a formula is embedded in calculated text:
={...} 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: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.
