I often encounter these three forms, but I'm sure that they are not always
interchangeable. Someone could explain me the difference and perhaps provide
me some example too?

question
grammar
What's the difference between というものではない、というものでもない and というわけがない?
For what i know, the first one mean "is not", the second one "Not even" and
the third one "There is no reason". They should be used in different context

Apparently they are covered regularly in foreigners' grammar e.g.
[this](https://nihongonosensei.net/?p=12824) or [this](https://nihongokyoshi-
net.com/2018/05/08/jlptn2-grammar-toiumonodewanai/). I assume you meant
というわけではない for the third item.

All three can be translated mostly _It is not that ..._.

Just one example:

  * 謝ればいいというものではない : It is not that saying sorry is enough.
  * 謝ればいいというものでもない : It is not really that saying sorry is enough.

The former sounds a bit stronger denial/disagreement for 'saying sorry is
enough', somewhat suggesting something else must be done. The latter sounds
softer, like _saying sorry should not be enough, but maybe nothing else should
be done either_.

というわけではない/というわけでもない are mostly synonymous to というものではない/というものでもない, but like
covered [here](https://chiyo-sampo.net/grammar-jlptn2-toiu-wakedewanai-2/), in
a structure with preceding ～だからといって, というわけで{は,も}ない may be more frequent.
(～だからといって～というもので{は,も}ない is possible).

===

わけない appears as form of [～わけがない](https://nihongokyoshi-
net.com/2018/04/16/jlptn2-grammar-wakeganai/), where が is omitted. Means _it
is impossible that..._.
