How can I check whether my paper follows the required ARR formatting before submission? [D]

Last cycle, one of my research paper was rejected because of formatting issues. I recently heard from someone that there may be a tool or software called something like “aclpubcheck” that can be used to check whether a manuscript follows the required submission format correctly.

Does anyone know the exact name of this software or tool?

Also, if there is no such reliable tool, what is the best way to make sure that a paper is formatted correctly before submission? Like, how do you usually verify margins, page limits, font size, template compliance, bibliography format, and other formatting requirements before submitting to a conference or journal?
