JonathanMa1, there isn't a way with the current CSV module to split tabs, that mod just looks at the first tab and its headers and you can parse that. There is a 365 Excel module but we're not able to connect and use that in our environment due to security lockdowns so I don't know if it has the ability to see tabs and data and allow you parse. Sorry this wasn't overly helpful, me someone that has used the Excel mod as additional insight to help.
