In JSON, an object (also called a “dictionary” or a “hash”) is an unordered set of key-value pairs. TO_JSON and PARSE_JSON are (almost) converse or reciprocal functions. The PARSE_JSON function takes a string as input and returns a JSON-compatible VARIANT. The TO_JSON function takes a JSON-compatible VARIANT and returns a string. The above df was created with column name “name” while the returned column name after collect() was called became “NAME”. It’s because the column is regarded as ignore-case so the Snowflake database returns the upper case. To create a Column object that represents a constant value, use snowflake.snowpark.functions.lit():
