How to use Replace Words with Digits
- 1. Paste the text with spelled-out numbers. Paste a sentence or passage containing numbers written as words into the input pane, such as a document that spells out quantities like 'three' or 'twelve'.
- 2. Read how the conversion works. The tool has no settings; it scans the text for spelled-out number words and replaces each one with its numeric digit form, leaving other words untouched.
- 3. Copy the converted text. Copy the result from the output pane, now with numbers in digit form, and paste it wherever a more compact numeric style fits, such as a data sheet.
When to use Replace Words with Digits
Replace Words with Digits turns spelled-out numbers in your text into their numeric form, so 'three' becomes '3'. Use Replace Words with Digits when a passage written in prose needs its quantities converted to digits for a form, spreadsheet or data field.
- Preparing prose text for a data entry field. A written report spells out quantities in words, but the system you're entering data into expects numeric digits, so converting the words first speeds up entry.
- Cleaning transcript text for numeric analysis. A transcript of spoken content has numbers written out as words, and converting them to digits makes the text easier to parse for any figures mentioned.
- Standardizing number style across a document. A style guide prefers digits over spelled-out numbers for a certain document type, and this converts every spelled-out quantity in one pass instead of manual edits.

Frequently asked questions
Is Replace Words with Digits free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.

How much text can I process at once?
