Ordinal to Number Converter

Every ordinal on a page hides a plain number underneath it: 1st is hiding 1, twenty-second is hiding 22, and one millionth is hiding 1,000,000. Recovering the number matters every time an ordinal lands in a spreadsheet, a database or a script — racing results, prize lists, edition numbers and page references are all stored as cardinals, and someone has to strip the ending and the words before the value can be counted, compared or summed.

Ordinal to Number Converter reverses the ordinal rules exactly. Type 113th and it returns 113; type one hundred and thirteenth and it returns the same number from the words. It reads suffix forms of any size, spelled-out ordinals up to the vigintillion scale, negatives, zeroth, and batches of up to 10,000 values in one pass — with thousands grouping for readability and BigInt arithmetic so nothing ever rounds. Everything runs in your browser, and nothing is uploaded.

• Both notations: Suffix forms (113th) and word forms (one hundred and thirteenth) parse in the same box, mixed freely.
• Any-size suffix forms: 12345678901234567890123rd parses exactly — no upper bound on the digits.
• Full English scale: Word parsing covers first through vigintillionth, a 63-digit range, with BigInt arithmetic.
• Hyphens and "and": twenty-second equals twenty second, and one hundred and first equals one hundred first.
• Case insensitive: FIRST, First and first all work; thousand separators like 1,000,000th do too.
• Negatives and zeroth: -7th and negative seventh both become -7; zeroth becomes 0.
• Batch mode: Up to 10,000 values per run, each parsed independently with clear error lines.
• Thousands grouping: Display 1,000,000 instead of 1000000 whenever readability matters.
• Copy or download: Take the plain numbers to the clipboard or save them as a text file.
• Free and private: Every parse happens locally in your browser; nothing is uploaded or stored.

1. Enter the ordinals — suffix forms like 113th, word forms like one hundred and thirteenth, or a batch of either separated by new lines, commas or spaces.
2. Choose the output style — tick "Group thousands" to display 1,000,000 instead of 1000000.
3. Read the results — each ordinal is matched with the plain number it hides, and a badge shows whether it was read as a suffix or as words.
4. Check invalid entries — anything unparseable is listed as an error line instead of silently dropping.
5. Copy or download the plain numbers for spreadsheets, databases or scripts.

Example 1 — A race results sheet. Paste 1st, 2nd and 3rd. The tool returns 1, 2 and 3 — the plain positions that can be ranked and compared.

Example 2 — The tricky teens. Enter 11th, 12th and 13th. The endings look odd but the answer is simply 11, 12 and 13, because these are the three numbers whose endings refuse the pigeonhole rules.

Example 3 — Words from a document. Enter one hundred and thirteenth. The tool parses the words, ignores the "and", and returns 113 exactly as the digits-only version did.

Example 4 — Spelling out what spreadsheets want. Enter twenty-second, one millionth and zeroth. The output is 22, 1,000,000 and 0 — the cardinal values a database actually stores.

Example 5 — A large mixed batch. Paste 1001st, negative seventh, 1,000,000th and one billionth together. Each parses independently: 1001, -7, 1,000,000 and 1,000,000,000, with grouping applied to every positive value.

• Exact reversal of the rules: Suffix logic and the 11-12-13 exception decode correctly in both directions.
• Words become numbers: Spelled-out ordinals parse without a single lookup table in your head.
• BigInt exactness: Values up to 63 digits compute exactly, with nothing rounded or truncated.
• Batch speed: Ten thousand mixed ordinals convert in one run, so pasted lists are one click.
• Friendly tolerance: Case, hyphens, "and" and commas are all handled, not rejected.
• Private and free: Parsing happens entirely in the browser; nothing is uploaded, stored or logged.
