Use the File component (in Storage) for this.

If you want to save data in csv format then separate each element with a comma (,) - there should be no other commas in your elements, and end the line with a “\n” (no quotes)

For cases where you might be missing values like phone number, you can use JSON format, which is generated automatically when you convert a dictionary data type to text format.
