Hello @Janusz Wiercimak,
Yes this is possible with the help of Html Macro Kindly have a look at the 2 articles https://confluence.atlassian.com/conf64/import-content-into-confluence-936510869.html
Hope this helps!!!!!!
I suggest this is only a partial solution.
The imported page can't be edited using the Confluence WYSIWYG editor. Any further mods require direct editing of the markup (HTML).
As of Confluence version 6.15.2, the only document format with first-class* import support is Microsoft Word.
Given their prevalence, isn't it about time HTML and Markdown import were given first-class* support in the core product?
* Subsequent editing via WYSWYG editor
You can use add-on to import HTML files: All-in-one File Importer for Confluence
It supports importing HTML files as well as ODT, LaTeX and many others. It supports multiple files at once, so if you have many files, you can import at once.
We are developers behind this add-on. Please give it a try and give us feedback if you see any issues. You can install from here:
Hi Pierre, you are right Asciidoc is currently not supported. We will have a look into this and will try to add support.
In the meantime as an workaround, you can convert Asciidoc to any other supported formats like Markdown and import using above plugin.
