Generally speaking, inversion structures are mainly used in very formal or literary contexts. They often sound awkward or outdated in regular conversation. English doesn’t have a clear conditional tense like some other languages, so conditional inversions are more about style and formality than strict grammar rules. You can write or speak formally without using inversion. In fact, inversion tends to be more common in “artsy” or literary formal language rather than straightforward business communication, which usually favors clearer, more direct phrasing.
A very loose rule of thumb is to use inversion when you would use a formal verb tense or structure in your native language, but it’s best reserved for writing or speech that requires emphasis or elegance.
