I waste time cleaning up formatting when I copy text between different places

I regularly copy text from different places such as Word documents, websites, plain text files and other tools.

The problem is that the formatting comes across differently every time. Headings are inconsistent, bullet points change, spacing is wrong and random formatting gets carried over.

I then have to go through everything manually and tidy it up before I can use it. I would like to be able to paste the text somewhere and have it cleaned up into one consistent format automatically.
