2 important options:

• delimiter: The delimiting character. Leave blank to auto-detect. If specified, it must be a string of length 1
• header: If true, the first row of parsed data will be interpreted as field names. An array of field names will be returned in meta, and each row of data will be an object of values keyed by field name instead of a simple array. Rows with a different number of fields from the header row will produce an error. Warning: Duplicate field names will overwrite values in previous fields having the same name.
