Spark SQL provides `spark.read().csv("file_name")` to read a file or directory of files in CSV format into Spark DataFrame, and `dataframe.write().csv("path")` to write to a CSV file. Function `option()` can be used to customize the behavior of reading or writing, such as controlling behavior of the header, delimiter character, character set, and so on.
