Okay so..

I know exactly how to make quests and all that shazaz however when it comes to exporting I have no clue..

I made the quests in a singleplayer world, exported them by copying the Local ftbquests folder and Defaultconfigs ftbquests folder from MY modpack and then pasting them into their corresponding folders in the servers modpack files.

I thought this should've worked however when entering the server world, none of the quests show for anyone.. I'm a little confused as to where I've messed up.

Please help 😞

Most likely, this is no longer relevant for you, but I will still leave my answer, because I had the same problem, and I did not find a clear answer anywhere. To ensure your server players have the quests you created, all you need to do is transfer the necessary files to the server. Players don't need to install anything on their end, except for mod. You need to find .minecraft>config>ftbquests>quests. In quests should be folder and two files. So all you need to do is use existing ones or create folders config>ftbquests>quests, and copy the contents of the quests folder.
