Ebook Check and Export Workflow for KDP
The check and export stage is where an AI draft either becomes publishable or starts to break. Review structure, metadata, images, TOC behavior, format choice, and Previewer results before the file leaves the workflow.
Many ebook tools treat export like the finish line. For KDP, it is closer to a controlled handoff. Amazon supports several manuscript formats, recommends Kindle Previewer for validation, and warns that format choice depends on the reading experience you are trying to deliver. This guide turns the final stage into a repeatable review instead of a last-minute guess.
Decide whether the project is reflowable, fixed-layout, or print-first
The first export question is not which button to click. It is what kind of reading experience the book needs. KDP separates reflowable ebooks from Print Replica and other layout-sensitive content because each behaves differently on Kindle devices and in conversion.
A standard nonfiction guide usually wants a reflowable path. A visual-heavy page set may need a fixed layout decision. A coloring book is generally a print-first interior problem, not an ordinary ebook conversion problem. AIeBookGen should preserve that distinction all the way to export.
Choose the manuscript format that matches the job
KDP currently accepts DOC or DOCX, KPF, EPUB, HTML, RTF, TXT, and PDF for ebook manuscripts. Amazon also notes that PDF support applies only to certain languages and that EPUB should be validated in Kindle Previewer before publishing.
That means EPUB is important, but it is not automatically the right answer for every project. Use EPUB or other reflowable-friendly inputs when the book must adapt to different Kindle screens. Use PDF or another layout-sensitive handoff only when the project truly depends on fixed positioning or print-first design.
The safest export is the one that matches the book's structure, not the one you happened to generate first.
Check structure before you check style
Before worrying about polish, review whether chapters, heading hierarchy, front matter, repeated blocks, and table of contents behavior still make sense. Structure problems often survive into export and become harder to diagnose later.
This is especially important when the content was generated in sections. AI-generated drafts can drift in naming, duplicate headings, or break the order of repeated chapter blocks. A structured pass catches those problems before they become file-format problems.
Review images, tables, and layout-sensitive content
Image-heavy books fail differently from plain text books. Captions can detach from their images, tables can become unreadable, large files can behave badly in conversion, and page rhythm can collapse when a layout-sensitive book is pushed into a reflowable format.
For cookbook pages, look for image placement and recipe consistency. For illustrated or activity content, check whether page-level relationships still make sense after export. For coloring book interiors, the line-art review belongs in the print handoff stage rather than being hidden inside an ordinary ebook export.
Keep metadata and disclosure notes attached to the handoff
The final file should not become detached from the listing work. Title, subtitle, description, keyword choices, categories, cover direction, and any disclosure notes should still be visible at the export stage.
That is why AIeBookGen should export a handoff, not just a download. The person doing the upload should be able to see what the file is, how it was packaged, and what still deserves human review.
Validate in Previewer, repair, and only then upload
Amazon recommends Kindle Previewer as the best way to validate EPUB content and preview how the book converts. It also explicitly advises authors not to sideload content to Kindle E-readers for testing reflowable books.
That guidance is useful even outside EPUB. A real export workflow should assume preview, issue spotting, repair, and another pass. The honest promise is not instant approval. The honest promise is fewer surprises between export and submission.
Recommended workflow
- 1
Pick the target output before the final pass
Decide whether the project should leave as a reflowable ebook handoff, a layout-sensitive export, or a print-first interior package.
- 2
Run a structure review
Check chapter order, heading levels, front matter, repeated sections, and table of contents behavior before touching visual polish.
- 3
Run a metadata and packaging review
Confirm that title, subtitle, description, keyword choices, categories, cover brief, and disclosure notes still match the manuscript.
- 4
Run an image and Previewer review
Check image-heavy pages, tables, lists, TOC behavior, and converted output in Kindle Previewer where applicable.
- 5
Export with notes, not only with a file
Keep the manuscript file, export assumptions, metadata notes, and remaining warnings together so the uploader does not have to reconstruct context.
Pre-export checks worth doing every time
| Area | Question to ask | Why it matters |
|---|---|---|
| Format path | Is this book really reflowable, fixed-layout, or print-first? | Prevents using the wrong export lane |
| Structure | Do headings, chapters, front matter, and TOC still read in order? | Prevents conversion confusion |
| Metadata | Does the detail-page language still match the actual book? | Protects reader expectations |
| Visual content | Do images, tables, and captions still work after conversion? | Reduces layout drift |
| Notes | What still needs human review before submission? | Keeps upload calmer and more accurate |
