Welcome to the 15th Excel Tutorial where I show you a bit more on data validation. Last time, I covered how to validate using dropdown lists, but there are more options, more ways to customize your validation items to fully idiot-proof your spreadsheets.

If you know how to validate using one option, you will know how to validate using the others. I go over the various settings, input messages, and Error Alerts. You can customize these settings to your heart's desire.

I hope you enjoy this quick tutorial and if you have any questions, feel free to ask.
