ISO 8601 is the international standard for date and time representations, used by most modern APIs, JSON payloads, and databases. The QdoShare ISO 8601 Formatter parses any valid ISO string into a human-readable form and generates correctly formatted ISO strings from a date picker — useful for filling out test data, validating API responses, or working with timestamps in your code.
