I would say that posting a spreadsheet for review would fail the first on-topic question: What topics can I ask about here?What topics can I ask about here?
Does my question contain embedded code?
That being said, and as discussed in Can we review spreadsheet formulas?, reviewing the formulas themselves, if one feels that their formulas are complex enough they would consider them as "code", can be OK, but the question would have to be tailored as such that you the OP is seeking a review of the formula(s) rather than the spreadsheet itself.
