Excel Data Validation For beginners

Keep bad data out of your spreadsheets

Excel's Data Validation feature is one of the most underused tools in the entire application, and this course walks through exactly how to put it to work. Instead of cleaning up messy spreadsheets after the fact, you'll learn to build rules that stop incorrect entries before they ever land in a cell.

What's covered

• Restricting numeric inputs to integers or decimals within a set range
• Building dropdown lists so users can only pick from approved values
• Applying date and time controls to keep entries within valid windows
• Setting up text-based rules to catch stray or malformed input

Who it's for

Anyone who shares workbooks with other people — team leads, analysts, small business owners — and is tired of fixing data entry mistakes after the fact. No prior Excel expertise is assumed; the course is built for beginners who already know their way around a basic spreadsheet.
