This APA Checker/Lint/Validator does miscellaneous checks for conformity with the American Psychological Association (APA) citation and format style.
To use it, simply visit the validator page. Paste in your APA document and hit the Validate button.
If you have a suggestion for a check, please file an issue for it. Or even better, submit a pull request. The source code is written in JavaScript, so it's easy for people to modify and send me patches and pull requests.
Chantal Mülders of Rotterdam Business School for suggesting numerous checks.
