Mustache and Handlebars

{{{toCSV list 'propertyName' 'quotes'}}}

Creates a csv of the array.
example{{{toCSV list 'name' '\"'}}} would take an array of object and use the name property with double quotes to create a csv, like this "Peter","Rickard"

{{toJSON object}} or {{JSONstringify object}}

Runs JSON.stringify(object) on the object.
Good to use in cases where you get an output like [object Object],[object Object]

example and object like this {payload:[{ value: "foo" },{ value: "bar" }]} with the mustache {{{toJSON payload}}} would resolve in [{"value":"foo"},{"value":"bar"}] instead of [object Object],[object Object]
