Formal:
* "Ça va" - This is the most common and neutral way to say "so ok" in French. It literally translates to "It goes," but it is used to inquire about someone's well-being and can also be used to express that you are doing fine.
* "Pas mal" - This translates to "not bad" and is a slightly more positive way to say "so ok."
* "Correct" - This means "correct" and is a more formal way to say "so ok." It implies that things are alright but not necessarily great.
Informal:
* "Pas trop mal" - This is a less formal way to say "not bad" and is a good option for friends or family.
* "Comme ci, comme ça" - This translates to "so-so" and is a good way to say "so ok" if you're not feeling particularly good or bad.
* "Moyen" - This means "average" and is a casual way to say "so ok."
Example:
* "Comment vas-tu ?" (How are you?)
* "Ça va, merci." (So ok, thank you.)
You can also use "assez bien" (pretty good), "bien" (good), or "très bien" (very good) depending on how you are feeling.
Remember that the best way to say "so ok" in French is to consider the context and choose the most appropriate option.
