In this video, you’ll learn how to create and use the Lookup table variable in Tag Manager to transform or standardize data values. We’ll show how to map input values to new outputs, helping you simplify or group inconsistent data. You’ll see how to select an input variable, define input–output pairs, and set a default value for unmatched cases. The video also demonstrates how to test your setup in debug mode to confirm that values are being replaced correctly. By the end, you’ll know how to use Lookup table variables to keep your data clean and consistent.
