Does my data get uploaded anywhere?
No. Everything runs locally in your browser and nothing is sent to a server.
Is this free to use?
Yes. It is completely free, with no account, no signup, and no usage limits.
Do I need to install anything?
No. The tool runs entirely in the browser, so there is nothing to download or install.
Are thousands separators handled?
Yes. A number written as 1,234.50 comes back intact, while a comma that is ordinary punctuation is left behind rather than stuck to the number. The output is ready to paste into a spreadsheet.
Will a phone number be read as a negative?
No. A hyphen only reads as a minus sign when it opens the number, so 555-1234 gives you 555 and 1234, and a range written 3-4 gives you 3 and 4. A real negative such as -7 is still recognized.
Does it keep decimals and currency?
Decimals yes, currency no. A price of 34.50 with a dollar sign in front returns as 34.50 without the symbol, because only the digits and the decimal point are captured.
Can it add up the numbers it finds?
No, it only extracts them. Copy the list, paste it into a spreadsheet column, and sum it there. The values come out clean, so there is nothing to strip first.
Will it handle numbers written with a comma as the decimal point?
Not correctly, because the comma is treated as a thousands separator. A value written as 3,5 is returned as the string "3,5", which most spreadsheets in an English locale will read as 35 or reject.
Is the text I paste kept anywhere?
No. Extraction runs in the browser, which matters when the source is an invoice, a bank statement, or a report you would not upload to a stranger's server.
