it looks like correct data types are not translated into SQL Developer when you are browsing a Snowflake table metadata in SQL Developer.
For instance, we are getting TEXT instead of VARCHAR.
In the picture below I have placed the same Snowflake table shown in SQL Developer vs Squirrel

columns are sorted and can be matched by position number.
Squirrel posts it as VARCHAR (original data type ) as in Snowflake, while SQL Developer shows it as TEXT which is not Oracle neither Snowflake data type.
