# init(hasHeaderRow:nilEncodings:trueEncodings:falseEncodings:floatingPointType:ignoresEmptyLines:usesQuoting:usesEscaping:delimiter:escapeCharacter:) Creates a set of options for reading a CSV file. ``` init(hasHeaderRow: Bool = true, nilEncodings: Set = ["", "#N/A", "#N/A N/A", "#NA", "N/A", "NA", "NULL", "n/a", "nil", "null"], trueEncodings: Set = ["1", "True", "TRUE", "true"], falseEncodings: Set = ["0", "False", "FALSE", "false"], floatingPointType: CSVType = .double, ignoresEmptyLines: Bool = true, usesQuoting: Bool = true, usesEscaping: Bool = false, delimiter: Character = Character(","), escapeCharacter: Character = Character("\\")) ``` ## Parameters `hasHeaderRow` A Boolean value that indicates whether the CSV file has a header row. Defaults to `true`. `nilEncodings` A list of recognized encodings of `nil`. Defaults to `["", "#N/A", "#N/A N/A", "#NA", "N/A", "NA", "NULL", "n/a", "null"]`. `trueEncodings` A list of acceptable encodings of `true`. Defaults to `["1", "True", "TRUE", "true"]`. `falseEncodings` A list of acceptable encodings of `false`. Defaults to `["0", "False", "FALSE", "false"]`. `floatingPointType` A type to use for floating-point numeric values (either [`CSVType.double`](/documentation/TabularData/CSVType/double) or [`CSVType.float`](/documentation/TabularData/CSVType/float)). Defaults to [`CSVType.double`](/documentation/TabularData/CSVType/double). `ignoresEmptyLines` A Boolean value that indicates whether to ignore empty lines. Defaults to `true.` `usesQuoting` A Boolean value that indicates whether the CSV file uses quoting. Defaults to `true`. `usesEscaping` A Boolean value that indicates whether the CSV file uses escaping sequences. Defaults to `false`. `delimiter` A field delimiter. Defaults to comma (`,`). `escapeCharacter` An escape character to use if [`usesEscaping`](/documentation/TabularData/CSVReadingOptions/usesEscaping) is true. Defaults to backslash (`\`). --- Copyright © 2026 Apple Inc.
