convert kindle to epub, then no TOC

[hobnail]

By TOC what I mean is the pop up table of contents you get when you click on its icon at the bottom left of the screen on the Kobo. I don't know where that comes from, I'm guessing it's the toc.ncx file.

Is there some setting I need to use so that I always get that TOC when I use calibre to convert from a mobi or azw3 file to epub?

Take a look at the KF8 file in the Calibre editor. You'll then be able to see why you didn't get an NCX ToC built.

Without seeing the code, there's no way to know why there was no proper ToC generated. Post an example of the Chapter header and the CSS that goes with it.

Is this eBook a single HTML file? Is it multiple HTML files? Is the code a mess?

That sounds as if the original ebook did not have a table of contents or properly marked chapter headers. Have you tried enabling Force use of auto-generated Table of Contents in the Table of Contents section under Conversion/Common Options?

You may want to check the Table of Contents segment of the calibre on-line manual which also discusses manually editing the table of contents which comes in handy where calibre is unable to create an usuable ToC. There are time when the Mark One eyeball is the only tool for the job.

If that is the case and if the eBook may be one HTML file, did the chapters split properly?

I did some experiments and it looks like it's because I have it set for epub 3 in the output options. For no particular reason, except for consistency I suppose, since I always use epub3 when starting something in sigil.

It's unfortunate that calibre doesn't also produce the toc.ncx file when the output is set to epub 3. In sigil I always generate one just before the final epubcheck.

For me as well, generating the toc.ncx from the navigation document is one of the last things I do when editing an epub3 with Sigil.

We do have to remember that for an epub3, the toc.ncx is allowed for compatibility with older reader code and is not required.

I think Calibre needs an option to allow NCX or not with ePub 3.

But the thing is, what does a conversion from KF8 bring when converted to ePub 3 instead of ePub 2?

I've converted many an ePub 3 to ePub 2 and lost nothing.
