    Properties

    delimiter?: Delimiter

    CSV field delimiter. If you want to parse TSV, specify '\t'.

    Detail restrictions are as follows:

    • Must not be empty
    • Must be a single character
      • Multi-byte characters are not supported
    • Must not include CR or LF
    • Must not be the same as the quotation
    ','
    maxBufferSize?: number

    Maximum internal buffer size in characters.

    This option limits the size of the internal buffer used during lexing to prevent memory exhaustion attacks. The buffer size is measured in UTF-16 code units (JavaScript string length). When the buffer exceeds this limit, a RangeError will be thrown.

    Set to Infinity to disable the limit (not recommended for untrusted input).

    10 * 1024 * 1024 (approximately 10MB for ASCII, but may vary for non-ASCII)
    quotation?: Quotation

    CSV field quotation.

    '"'
    source?: string

    Source identifier for error reporting (e.g., filename, description).

    This option allows you to specify a human-readable identifier for the CSV source that will be included in error messages. This is particularly useful when parsing multiple files or streams to help identify which source caused an error.

    Security Note: Do not include sensitive information (API keys, tokens, full URLs) in this field as it may be exposed in error messages and logs.

    parseString(csv, { source: "users.csv" });
    // Error: Field count exceeded at row 5 in "users.csv"

    undefined
