Notes
-
Nested JSON arrays or objects in the array arguments are converted into text strings using your data platform’s JSON-to-text method. This can impact the nested JSON structure, key-value pair order, and white space (like spaces, tabs, and line breaks).
-
If any argument is
null, the function returnsnull.
