Data Validation provides your users with convenience in the form of drop-down lists, but more importantly, it provides you with protection against those unruly users who try to enter any old data into a cell by ensuring the data entered meets criteria you set. As a result, you spend less time fixing messy data that was entered incorrectly in the first place and have more time to create the clever interactive techniques Nabil covers in this comprehensive guide to Data Validation.

It’s thrilling to see this topic covered in such great detail. Data inputs and data quality aren’t as sexy as AI or data visualization, but data quality is important no matter what’s being done with data. And data validation is critical in supporting data quality. I’m so glad to see Nabil take this on. He’s a fantastic instructor and an experienced data professional. A true warrior in the battle to keep data clean and useful.
