How to transfer Minecraft: Java Edition worlds to Minecraft Bedrock (PE/Win10/Xbox/Switch)?

I have some worlds that I've been playing on for 3 years now and I would like to continue on them in the bedrock version. Is there anyway to FULLY transfer the worlds? BTW I'm not a stranger when it comes to technical stuff so if it requires skill to do it I can do it. I have also tried MCedit and MCC and both were unsuccessful. If you can't fully transfer the worlds then please tell me alternative methods.

Nevermind, too anyone looking at this in the future having the same problem, MCC did work! Search up the tutorials and make sure to use an old pe world that 1.0 to 1.1. Hope this helps!
