array : list or Array

Specifies the data struscture to use for parsed data corresponding to YAML arrays (sequential data delimited with square brackets). With array=list (the default), a YAML array is encoded as a list; with array=Array, it is encoded as an Array.

object : one of equationset, DataSeries, record, or table

Specifies the data structure to use for parsed data corresponding to YAML objects (collections of key/value pairs delimited with curly braces).

With object=table (the default), an object is encoded as table; with object=record, it is encoded as a record; with object=DataSeries, it is encoded as a DataSeries.

output : one of equationset, DataSeries, record, or table

A legacy alias for the object option.

ParseString(yamlString) parses the input string yamlString, which is assumed to be valid YAML.

with(YAML):

data := ParseString("[{\"fruit\": \"orange\", \"count\": 23}]");

$\left[\mathrm{table}\left(\left[''fruit''=''orange''\,''count''=23\right]\right)\right]$

data[1]["fruit"];

$''orange''$

dataRec := ParseString("[{\"fruit\": \"orange\", \"count\": 23}]",output=record);

$\left[{\mathrm{Record}}_{\mathrm{packed}}\left(\mathrm{fruit}=''orange''\,\mathrm{count}=23\right)\right]$

data[1]["fruit"];

$''orange''$
