7 min readTo convert a hashmap to a CSV file in Kotlin, you can iterate over the key-value pairs in the hashmap and write them to a CSV file using a CSV writer library such as Apache Commons CSV or OpenCSV. First, create a CSV writer object and write the header row with the keys of the hashmap. Then, iterate over each entry in the hashmap and write the key-value pairs as a new row in the CSV file. Finally, close the CSV writer to ensure that the file is properly saved.
