This might sound geeky - Help with creating an addon!
 

Hello

I am looking for someone, who can create something for me. I am playing on the World of Warcraft server Argent Dawn, whom some may know is a roleplay server. We have created this sheet in excel, based on a DnD inspired system, which we would like to bring into World of Warcraft somehow through an addon. If someone can us do this please reply. It is a complicated excel sheet, but if you think you are up for the task, and will help us out with this challenge, please feel free to contact me!

Your regards

I'm not sure if you're wanting someone to create an addon with data based off the spreadsheet or create an addon that reads from the spreadsheet. If it's the 2nd option that is not possible. Addons cannot read anything outside of the lua/toc/xml/savedvars.

You would really be better off sticking to something like Google Sheets, if the spreadsheet is meant to be updated regularly and meant to be accessible by several different people.

You can't just upload addon data to the servers for it to be accessible by all members, and syncing it between everyone would be a nightmare because you'd have to rely on the right people being online at the right times, and hoping they had the up-to-date version of the spreadsheet in their saved variables.
