Extract Numbers

How Extract Numbers works

Extract all numbers from text, including decimals and negatives, with optional de-duplication. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

What the pattern matches

The default pattern is a signed number, optionally with a decimal part — so 42, 1299.50 and −7 all match, while a date like 2026-11-11 comes out as three separate numbers.

Turning decimals off drops the fractional part, which is what you want when you only need whole counts from a mixed list.

Where it is genuinely useful

Pulling every amount out of an invoice or a bank statement pasted as text, collecting measurements from a spec sheet, or assembling a list of IDs from a page that mixes them with prose.

Unique mode de-duplicates, which turns a long paste into the distinct values you actually need to count.

The limitation worth knowing

It cannot tell a year from a quantity from a price. Every number is extracted in the order it appears, so context is your job — usually by pasting a narrower block rather than a whole page.

Good to know

• Works offline once loaded, including on flights and in locked-down networks.
• No file size limit beyond your device's own memory.
• Free to use, with no account and no usage counter.
• Results are produced locally, so they are not logged or shared with anyone.
