Default Format Markdown + Batch convert specific file types to Markdown

I’m sure that the MD dialect understood by DT is mentioned in the documentation. As to obsidian, that should be explained at their website.
If something does not work as expected, it is advised to

  • explain what one did
  • explain the expected output
  • explain what happened instead

With as much context as possible and needed.
Eg (something) in a MD file is probably considered to be part of a link:
[text](https://...) so it could well be that obsidian escaped the parenthesis because you didn’t.
