How to Use Keep Only Numbers
Paste any messy text into the box, and every character that isn't a digit is stripped out instantly — letters, spaces, and most punctuation all disappear. Leave "Preserve decimal points and minus signs" checked to keep values like -19.99 intact, or untick it to leave only the bare digits, which is handy for extracting something like a clean phone number or ID.
Example
"Call us at (555) 123-4567 or check your balance: -$42.50" becomes 555123-4567-42.50 with decimals and minus signs preserved, or 5551234567 4250-style digits only with that option unticked.
Common Use Cases
- Extracting a clean phone number or ID from messy pasted text.
- Pulling a numeric price or measurement out of a sentence or label.
- Stripping formatting characters out of copied spreadsheet or form data before reuse.
FAQs
- Will it keep the minus sign in a negative number? Yes, if "Preserve decimal points and minus signs" is checked — every hyphen/minus character in the text is kept, though note that in text with multiple dashes (like a formatted phone number), all of those dashes are preserved too, not just ones meant as a negative sign.
- Does it keep commas used as thousands separators? No — commas are always removed; only digits (and optionally the decimal point and minus sign) are preserved.
- Can I use this to clean up a pasted phone number? Yes — untick the decimal/minus option to strip parentheses, spaces, and dashes down to plain digits, giving you a clean number ready to dial or store.
