words-to-numbers

Converting words to numbers translates spelled-out values like "two hundred forty-two" into the numeric form 242. Common in form processing (cheques, contracts, OCR), accessibility (screen-reader output), and bilingual data cleanup. The ZTools Words to Numbers converter handles English (cardinal and ordinal), Spanish, and French up to numbers in the trillions. Decimal expressions ("two and a half"), fractions ("three quarters"), and mixed forms ("two hundred and three thousand four hundred fifty-six") are supported.

Use cases​

Parse cheque amounts​

Cheques have both numeric and written amounts. After OCR, validate that "one hundred fifty" matches "$150". Words-to-numbers does the comparison.

Clean dictation transcripts​

Transcripts say "twenty twenty-six" for years; downstream systems want 2026. Convert.

Multilingual form processing​

A French form has "trois cent vingt"; convert to 320 for analysis.

Build voice-to-data pipelines​

Voice assistant captures "five thousand"; downstream handler wants 5000.

How it works​

  1. Paste text — Sentence, paragraph, or just a number-word.
  2. Pick language — Auto-detect, or force English / Spanish / French.
  3. Convert — Tool tokenises, identifies number-words, replaces with digits inline. Non-number words preserved.
  4. Read result — Original text with numbers replaced. Edge cases (ambiguous words) flagged.

Examples​

Input: "I have two hundred forty-two apples"

Output: I have 242 apples.

Input: "Three thousand four hundred fifty-six dollars"

Output: 3456 dollars.

Input: "Two and a half"

Output: 2.5.

Input: Spanish: "ciento cincuenta"

Output: 150.

Frequently asked questions​

Does it handle ordinals (first, second, third)?

Yes — first → 1, twenty-third → 23. Toggle "ordinal mode" if you need them as ordinals (1st, 23rd) rather than cardinals.

What about millions / billions?

Up to trillions in long-scale (US/UK modern) or short-scale notation. Toggle the scale per language convention.

Decimal numbers?

"Three point one four" → 3.14. "Half" / "quarter" → 0.5 / 0.25.

Edge cases like "a couple"?

"A couple" → 2, "a few" → 3, "a dozen" → 12 (toggle "loose match" for these). Strict mode rejects ambiguous words.

Privacy?

All conversion in browser.

Tips​

  • For cheque processing, validate both directions — words → numbers AND numbers → words — and confirm they match.
  • Multilingual? Auto-detect works for clear cases; force the language for short ambiguous strings.
  • For "ten million two hundred thousand" style, the converter parses left-to-right; complex expressions might need pre-cleaning.
  • Combine with a numbers-to-words tool to round-trip and verify accuracy.
