Each is dual function - pass in (for example) and get out a js object, pass in a js object and get back out the xml string. The CSV node must be configured with a column template that specifys the required property names for that column (csv->js), or the properties of the object that should be made into the csv (js->csv)

<p>A function that parses the <b>msg.payload</b> to convert csv to/from a javascript object. Places the result in the payload.</p>
|
|
<p>If the input is a string it tries to parse it as CSV and creates a javascript object.</p>
|
|
<p>If the input is a javascript object it tries to build a CSV string.</p>
|
|
<p>A columns template MUST be specified that contains the ordered list of column headers. For csv input these become the property names.
|
|
For csv output these specify the properties to extract from the object and the order for the csv.</p>
|
|
<p><b>Note:</b> the columns should always be specified comma separated - even if another separator is chosen for the data.</p>
