Handling Missing Data & Data Validation in Excel
In this video, we will learn how to fill in missing values in Excel and set up data validation to keep entries consistent. This tutorial uses a fictional student dataset to rebuild missing email addresses with nested IF, CONCAT, and LOWER formulas; fill blank cells using Go To Special; and populate a missing country column with a lookup table and XLOOKUP (with a look at its optional arguments and a comparison to VLOOKUP/HLOOKUP). It closes with creating drop-down lists and error messages using data validation.
