Changing data type

CDP Data Visualization allows you to change the effective data type of a column in the dataset model without changing the source data. This is useful in many business environments to ensure correct processing of numerical codes, catalog numbers, event IDs, dates, and so on.

The following steps demonstrate how to change the type of a column. We are using the column iso_cc (the ISO-compliant country code) in the dataset World Life Expectancy [data source samples.world_life_expectancy].

  1. On the main navigation bar, click Data.
