The November update for's iCalendar validator adds JSON support. JSON is a data format that is typically used by JSON supported web applications to provide data processing when the HTML formatted data is not sufficient. Third party debugging tools are one example. JSON support is available when validating by URL, where two permalinks are now displayed: one for the HTML formatted results of the validation and one for the JSON formatted results.  The JSON permalink is simply the HTML permalink with the string "&json=1" appended to it.

JSON support adds another unique feature of our validator. We strive to have the best iCalendar validator available today on the web with continued support and development of enhancements like this one.
