Is as per check correct grammar?

"As per check" is not grammatically correct. It's a common phrase used in informal communication, but it's not standard English.

Here's why:

* "As per" is an informal way of saying "according to." It's best to avoid using it in formal writing.

* "Check" is too vague. It doesn't specify what kind of check or what information it contains.

Here are some better ways to phrase it:

More formal:

* According to the check

* Based on the check

* As indicated by the check

More informal:

* The check shows

* The check says

Example:

* Incorrect: "As per check, the balance is $100."

* Correct: "According to the check, the balance is $100."
