Free opening-hours tools

Each one takes the same messy input — the sentence a business actually wrote — and gives you one specific output format. No signup, no key, runs in your browser against the public API.

schema.org opening hours generator — Generate LocalBusiness JSON-LD from plain-text hours.
OSM opening_hours converter — Convert plain-text hours to OpenStreetMap opening_hours syntax.
Business hours to JSON converter — Turn free-text hours into per-day JSON intervals.
Hours of operation table generator — Generate an accessible HTML hours table you can paste into any site.
Opening hours validator — Check hours text for unparseable, missing or contradictory days.
WordPress opening hours JSON-LD generator — Get a complete, paste-ready ld+json script tag for your CMS.

Need it in your own code instead? The OpenHours API returns all three formats from a single POST, with a bulk endpoint for up to 500 strings per call.
