Letter question!!

[rachxo]

Is this correct? I would like to say thank you for correcting my Japanese sentences that had mistakes....

返事ありがとうございました！そして、私の違うの文を正しいすることありがとう。


Also, how would I say casually, "It would be great to have to you check my Japanese sentences."


Arigatou!

返事ありがとうございました！そして、私の違うの文を正しいすることありがとう。

返事 is one of those words that can be made politer by adding ご in front of it, but level of politeness will of course depend on what kind of relationship you have with the person who you are corresponding with.

ご返事をありがとうございました！そして、私の間違った文を正しく直してくれてありがとう。

I've just made a couple of changes which I think would be more grammatically correct and natural but your sentence was perfectly understandable.

Also, how would I say casually, "It would be great to have to you check my Japanese sentences."

また、私が書いた日本語の文章を確認してもらえばとてもありがたいです。

I'm not Japanese so I can't say how natural this sounds, but it should do if you can't get a better answer out of someone.

Thank you so much! You really helped me.
