To normalize customer data in a staging data extension where a text field named 'birthday' contains date values in various formats, the developer can use the following SQL keywords and functions:

CASE, ISDATE, CONVERT (A)- These functions can be used to handle different date formats and convert them into a consistent format.

CASE, ISDATE, CAST (C)- Similar to the above, CAST can be used to convert text to date format if ISDATE returns true.

Example SQL query:

SELECTCASEWHENISDATE(birthday)=1THENCONVERT(DATE, birthday)ELSENULLENDASnormalized_birthdayFROMStagingDataExtension

Platform.Function.ParseJSON();- To parse the retrieved JSON data.

Platform.Function.UpsertData();- To upsert the parsed data into a data extension.

Example code snippet:

varresponse =Platform.Function.HTTPGet("https://api.customer.com/data" );varjsonData =Platform.Function.ParseJSON(response);Platform.Function.UpsertData("DataExtensionName", ["PrimaryKeyField"], jsonData);
