How to convert to an Epub file without css and class?

Thanks. I just want the file to contain only the features I want. Css and Class are not the functions I want, and they cause some interference when editing files.

Sorry, but that doesn't make sense. The CSS is what sets how each tag is displayed. And the class attribute defines which class to use in the styleheet when you don't want the standard for that tag.

And from the point of view of editing an epub, most of my time is spent getting the styles correct. Editing of the actual text should be done elsewhere and then converted to appropriate publishing formats. Then those are tweaked to solve problems that the conversion cannot handle.

Maybe the question I should have asked was: What are you actually trying to achieve?

pure txt do not have toc. markdown support toc, but I haven't find a book reader support reading markdown files

Shameless plug: if you're trying to convert a single Markdown file, you might find my Markdown Sigil plugin helpful.
It is not as sophisticated as the Calibre text filters, but it won't add any styles to the epub.
However, it won't automatically generate a TOC, but if you used the proper Markdown heading syntax, all you have to do is select Tools > Table of Contents > Generate Table Of Contents.

Just convert to EPUB, delete the CSS file, and use "Cleanup CSS function" - it should remove useless "class" attributes.

I think I have said it before. I want the toc function of epub. The directory analysis of txt files by e-book reading software cannot meet my needs, and markdown files are not yet supported by most reading software (in fact, I have switched to markdown to store and read e-books on my computer) .

Which doesn't actually answer my question. Or at least not clearly. What it says is that you do not believe that ePub is a good format but are forced to use it in certain circumstances. So, why are you worried about removing the CSS? You are planning to read the book and the delete it. What you should be doing is creating a stylesheet that matches the styles used by whatever reader you are using for your markdown versions, putting that in the epub so that when read on the device you get your preferred experience.

And as to "markdown files are not yet supported by most reading software", that is because it doesn't do a lot of the things people want. Which you clearly know as you want the ToC that epubs do deliver.

When you convert to ePub, you don't get any unused CSS. CSS is not useless. Without it, I would not be reading eBooks as I do not like the format I get from just the defaults.
