Nicaea did not decide the canon
The Council of Nicaea met in 325 and its business is a matter of record. It addressed whether the Son is of the same being as the Father, the question that produced the creed. It set a common practice for the date of Easter. It dealt with a schism in Egypt and passed twenty administrative canons about clergy and church order.

It did not rule on which books belong in the Bible. The subject does not appear in the creed, in the canons, or in the accounts of the proceedings written by people who were there.
Where did the story come from? A legend recorded centuries later, in a ninth-century Greek digest of church councils, has the disputed and undisputed books placed beside an altar and the genuine ones jumping on top by themselves. It is a pious tale about a council that had already happened, not a report. Voltaire retold it with obvious relish in the eighteenth century, and a bestselling novel in 2003 put a version of it in front of millions of readers who had no reason to check.
This matters beyond trivia. If a council had decreed the list, the question who decided would have a simple answer and a troubling one. The real answer is stranger: nobody decided, in that sense, and the list was substantially in place before any council discussed it.
