is there a way to check and validate data? I have webshop traffic data in my spreadsheet on a daily basis. These are divided into our different channels like SEA, Price Search Engines, SEO and so on. I'm looking for a way to check if there are major discrepancies in new data compared to previous ones. In this way I would like to check whether we have tracking and/or transmission errors and then send a message to the responsible employee if necessary. Maybe someone has a good idea how I can implement this.
