About わけではない
As mentioned in the 訳だ grammar point, わけ is a noun that is used for strong determination/conclusion in Japanese, in the same way that 'so' is in English. Naturally, this determination may sometimes be negative, as is the case with わけではない. ではない being the conjugated form of the auxiliary verb だ, the adverbial particle は, and the い-Adjective ない.
わけではない may be translated as 'it doesn't mean that (A)', or 'it's not the case that (A)'. Although, 'it is not necessarily so that it's (A)', or 'so it's not (A)' are closer to the actual nuance of わけ. わけではない can be used at the end of any sentence, so long as the word before わけ is in attributive form.
As always, では may be replaced by じゃ.
Fun Fact
わけだ and わけではない match the explanatory meaning of 'so' in English that often replaces words like 'because' and 'since'. However, as we will examine in more detail in the わけがない grammar point, わけ also matches the emphatic nuance of 'so', as can be seen in statements like 'it's SO not (A)'.
- あなたの事が嫌いというわけではない。It's not necessarily so that I dislike you. (But I sure don't love you)
-
あなたの事が嫌いというわけがない。I so don't dislike you. (I don't dislike you at all)

So it says that じゃない can be used too but in polite speech would it be more common to say
じゃないです or ではないです
What about in informal speech?

I think the answer to this is “yes,” but is わけでもない more or less just a more emphatic version of わけではない? Here’s a context sentence:
(From Boundary Gate: Daughter of Kingdom, a 1997 PC-FX game)

I got the following sentence in my reviews:
A: 「また試合に負けたよ。もう我慢できない!泣いちゃいたい!」
B:「いつもうまくいくわけではない 。失敗はつきものだ。」and confused it with the “というわけではない” grammar point, which was marked as a wrong answer.
It seems like “という” in this sentence would at the very least be redundant, so my questions are: 1) would it also be grammatically incorrect, and 2) are these actually two separate grammar points?
Any help appreciated!
