Frequently asked questions

What should I check before using the output?

Case rules do not determine proper names, grammar or language-specific editorial style.

What if a file or action is unsupported?

Check the input format and any visible error, try a smaller test case, and confirm the browser supports the required feature. Do not treat an empty output as a successful result.
