kr_amount_to_koreanWrite a won amount in Korean words exactly: reading form ("백이십삼만 사천오백육십칠 원", spaced every 만 per Korean orthography), contract/receipt form ("일금 일백이십삼만사천오백육십칠원정"), and mixed form ("123만 4,567원"). Whole numbers below 10^20.
kr_korean_to_amountRead a Korean money expression as an exact number: "1억 2천만 원", "삼백오십만원", "일금 일백만원정", "2.5억", "12만3천". Returns digits and comma form.
kr_business_number_checkValidate the format and check digit of South Korean business registration numbers (사업자등록번호, 10 digits, NTS weights 1,3,7,1,3,7,1,3,5) and format them as 123-45-67890. This is an offline checksum test only: it does not tell whether the business is open or closed.
kr_ageCompute international age (만 나이, the legal standard in Korea since June 2023) and year age (연 나이, used by the Youth Protection Act and military service) on a reference date. Input a birth date, or the first 7 digits of a resident registration number (YYMMDD-G) to also get sex an…
kr_phone_formatNormalize South Korean phone numbers (mobile 010, Seoul 02, regional 031-064, 070, 050x safe numbers, 15xx/16xx/18xx company numbers) to one style. Restores a leading 0 dropped by Excel, converts +82, keeps extensions. Unknown shapes return null.
kr_address_splitSplit South Korean addresses into province/city (시도, normalized to the official name such as 서울특별시), district (시군구, including 일반구 like 수원시 영통구), base address (road name + building number) and detail (unit). Handles leading postal codes and addresses written without spaces. Rule-…
kr_name_splitSplit Korean full names into family name and given name, recognizing two-character surnames (남궁, 황보, 제갈, 선우 …). Flags names that are ambiguous from the characters alone (선우진 = 선 + 우진 or 선우 + 진). Latin-script names use the last word as family name.
kr_mask_piiMask Korean personal data before you store, log or share it. Text mode finds and masks resident registration numbers (900101-1******), phone numbers (010-****-5678), emails (ab****@x.com) and 16-digit card numbers inside free text. Item mode masks given values by kind, including…
kr_legal_deadlineCompute when a period expires under the Korean Civil Act (arts. 155-161), the default rule when a law or contract does not say otherwise: the first day is not counted unless the period starts at 00:00; weeks, months and years follow the calendar and end the day before the corres…
kr_text_countCount Korean text exactly: characters with and without spaces (as Korean job sites count 자기소개서), lines, words, UTF-8 bytes, NEIS school-record bytes (Hangul 3, ASCII 1), and SMS/LMS bytes with the message type. Models see tokens, not characters, so use this instead of estimating…
kr_relative_dateTurn a Korean relative date expression into an exact date and weekday, counted from a base date in Korea time: 오늘/내일/모레/내일모레/글피, 어제/그제, "3일 뒤", "이틀 후", "2주 후", "한 달 뒤", "3영업일 후", "다음 주 화요일", "지난주 금요일", "이번 주말", "금요일", "다음 달 말일", "이번 달 25일", "내년 3월 1일", "연말". Weeks start on Monda…
