HTMLZ - Single HTML File Output

Sigil is often the solution given around these parts but some people insist on the need for a book to be contained in a single HTML file. Simply unzipping an EPUB doesn't accomplish this due to the need to split the files.

To remedy this situation I've added a new output format: HTMLZ.

Thanks for that, been waiting for this for a long time. However, how does it work?? (please note I am not a developer of HTML expert).

What I did is that I unzipped the HTMLZ file (using 7-zip). Edited the index.html file and dragged it back into 7-zip.

I then "Added" the HTMLZ file back to Calibre and tried to convert it, but it just wouldn't work.

What did I do wrong?

TIA

What error message did you get when you tried to convert?

This is what I did:

1 - Extracted all files from HTMLZ using 7-zip to new folder
2 - edited index.html using Word 2010, made one change and saved as HTML Filtered
3 - Dragged index.html back to 7-zip and closed 7-zip
4 - Used Calibre "Convert Books" to convert from HTMLZ to MOBI.

This is the resulting log:

Fixed. I'm not sure I got the fix in time for it to be included in the 0.7.55 release.

The issue is I forgot to handle the input encoding. It assumes the document is encoded in utf-8. Until the fix is released, when you save your HTML file save it using utf-8.

Thanks user_none. Absolutely fantastic. Works like a dream.
And thanks a ton for doing this work. It opens a whole new range of opportunities for me (and others of course )

Hello, user_none -

I'm so grateful you've taken the time to find a way to convert non-DRMed Kindle files into html so that we can edit some of the content. I'm on Mac OS X 10.5.8, and I have a question. Once I unzip the htmlz file, is there a preferred editor I should use? I read above about someone editing in Microsoft Word, but I find that MS Word tends to screw up any HTML code. Is there something else you can suggest?

Editpad Lite is pretty good (and free). Just Google it for download.

Notepad++ is open source and has syntax highlighting.
