How it works
- Paste mixed text or use the loaded business-report example.
- Select all values or narrow the results to integers, decimals, percentages, or currencies.
- Choose line, comma-separated, or JSON output and optionally remove duplicates.
- Copy the live result or download it as a text file.
The matching method
The scanner uses one ordered numeric pattern: an optional sign, an optional supported currency symbol, grouped or ungrouped digits, an optional decimal part, and an optional percent sign. Results are then filtered by their visible syntax rather than converted, so formatting such as “$128,450.75” is preserved.
FAQ
Which number formats can it find?
The scanner recognizes signed integers, decimals, thousands separators, percentage suffixes, and values prefixed with $, €, £, or ¥. Filters can narrow the displayed results.
Is the pasted text uploaded?
No. Matching, filtering, formatting, copying, and file creation all happen locally in your browser tab.
Does it calculate or change the values?
No. It preserves each matched string as written, including signs, currency symbols, commas, decimal places, and percentage marks.
How are duplicates handled?
Duplicates are kept by default so the output reflects every occurrence. Turn on Remove duplicates to keep only the first occurrence of each exact matched string.
Can I use the output in a spreadsheet or script?
Yes. Choose comma-separated output for a quick row, JSON for code, or one value per line for pasting into a spreadsheet column.
