I create mathematics workbooks in Microsoft Word. Typing in each equation is slow but faster than LaTex. So, I often copy content from a website like LibreTexts. If I copy a section that contains equations it comes out garbled. So, I go to each equation, right click, hover over Show Math As, select MathML code, select all (Ctrl+a), copy (ctrl+c), close window (Ctrl+w), go to word (Alt-Tab), paste as plain text (Ctrl+Shift+v), go back to Chrome browser (Alt-Tab), then repeat the process.
This can be faster than typing by hand, but there has to be an easier way. There was a post similar to this one, but I don't know what extension was referred to and I don't know java.
If your solutions contains the step "learn basic Java here", that is fine. If this is the incorrect Stack Exchange, please suggest the correct one.
Thank you.
