The product materials describe several document and ebook export formats, including Word, EPUB and PDF, with Google Docs also mentioned in the feature listing. Format availability is useful, but a file extension does not prove the exported book is ready for every destination. Check the exact plan and current export behavior, then open a representative file in the editor or publishing preview you actually intend to use.
Look at headings, paragraph styles, tables, lists, footnotes and navigation. Can an editor make changes without fighting the document structure? Does the table of contents lead to the right sections? Are special characters and links preserved? A visually attractive PDF may be a poor starting point for a reflowable ebook, while an editable manuscript may still require substantial print-layout work. The right export depends on the next job, not the most impressive label in a menu.
Amazon's quality guidance recommends reviewing ebooks in Kindle Previewer and checking issues such as formatting, navigation and readability. Apply the same principle to any destination: inspect the reader-facing result, not only the source document. Increase text size, examine narrow screens and test the important links. These checks can reveal problems that remain invisible in a desktop document view where everything has plenty of room.
Keep the editable source, final export and a record of corrections together. If a late change is needed, make it in the right source and regenerate the deliverable rather than creating several inconsistent final versions. Publishing work often becomes confusing at exactly this handoff. A drafting tool is more valuable when its output enters a manageable editing process, not when it leaves the author with four files named final and no certainty about which one contains the corrected chapter.
