Option escape

The escape option set the escape character as one character/byte only. It only applies to quote and escape characters inside quoted fields.

The default value is " (double quote) when no option is provided and when the value is undefined or true. The values null and false disable escaping.

• Type: Buffer|string|null|boolean
• Optional
• Default: "
• Since: 0.0.1

Default behavior

The default example doesn't need to declare the escape option. It is activated by default with the " character. Note how it only apply inside a quoted field.

import assert from "node:assert";
import { parse } from "csv-parse/sync";

const data = `a,"b""c",d`;
const records = parse(data);
assert.deepStrictEqual(records, [["a", 'b"c', "d"]]);

Custom behavior

The custom example change the default behavior by setting the escape character to \ (backslash).

import assert from "node:assert";
import { parse } from "csv-parse/sync";

const data = `a,"b\\"c",d`;
const records = parse(data, { escape: "\\" });
assert.deepStrictEqual(records, [["a", 'b"c', "d"]]);
