Business hours to JSON converter

Scraped or user-entered hours arrive as prose. Get back a predictable object: seven days, each with an intervals array of open/close times in 24-hour form, plus a confidence score and anything that failed to parse.

…

What the parser handles

• Ranges and lists of days: Mon-Fri, M-Th, Sat & Sun, weekdays.
• Loose time formats: 9, 9am, 9.30, 09:30, noon, midnight.
• Split shifts, overnight hours that cross midnight, closed, by appointment, 24/7.

Confidence and unparsed segments

The response includes a confidence float and an unparsed_segments list. The parser is deterministic — no LLM — so it never invents hours; anything it can't read is handed back to you for review instead of being silently guessed.

Do this at scale

This page runs on the public OpenHours API. The same call handles bulk input — up to 500 hours strings per request — and returns all three formats at once. Free tier is 100 requests/day with no signup.
