You have a few options for proceeding if you've already written content in Word.
- Create a new book and select the option to share a folder with Leanpub using Dropbox. That way, you can put your Word files in a folder you share with Leanpub, and then list your files in a file called Book.txt that we create for you. That way, you can write on your computer as you normally would, and then go to Leanpub to create previews and publish your book without any uploading or converting.
- Create a new book and select the option to upload a Word document. Then, you can save all your writing in a single Word file and upload it to Leanpub. You can upload a new Word document again later if you want to make any changes or publish your book in-progress. There is some information about this process here.
- Create a new book and select the option to share a folder with Leanpub using Dropbox. Then, select "Import" from the book tools on the left and click on HTML. Now, if you save your Word document as HTML, you can upload the file here and convert it to plain text and Markdown. There are some instructions for how to do this here.
We welcome authors who write in Word, but thought we'd take the opportunity here to explain our position on writing books in the digital age. We believe that writing in plain text and typing out your formatting instructions in a markup text is a better way to write books than Word, OpenOffice, DocBook, anything. This way of writing is purer, because your manuscript is 100% text, without being wrapped in the computer code that, say, Word uses to make a letter appear bold, which can change or become obsolete. It means that from a single source text, you can easily produce well-formatted ebooks in PDF, EPUB, MOBI, and HTML formats. Also, Leanpub is based on the idea that publishing while you write is helpful. We call that idea "Lean Publishing"; see the manifesto for the full spiel :)
