For example to write =MEAN($C$2:C@Value(_result)), where result is another attribute.
I tried with text, varchar attribute types when writing but didnt work.

Using your formula I was able to write to both the new and old XLS writers, the attribute data type is string.

I realize this is an old question, but none of the existing replies helped me find the answer (thankfully it was documented).
You need to store the formula in a separate attribute named <AttributeName>.formula
So if you want a column named Total to be the result of a formula, create an attribute called Total.formula and populate it with your formula, e.g. =SUM(A2:B2)
