Stream Results are delivered row by row to a step function. Use with large inputs that would crash the browser. Worker thread Uses a separate thread so the web page doesn't lock up. Header row Keys data by field name rather than an array. Dynamic typing Turns numeric data into numbers and true/false into booleans. Skip empty lines By default, empty lines are parsed; check to skip.

Delimiter:tabThe delimiting character. Usually comma or tab. Default is comma. Preview:If > 0, stops parsing after this many rows. Encoding:Only applies when reading local files. Default is specified by the browser (usually UTF-8). Comment char:If specified, skips lines starting with this string.
