Number Extractor
Extract signed, decimal and scientific numbers, including both values in a compact range such as 5-8, without splitting dotted versions or IP addresses.

Extract signed integers, decimal values and scientific notation, including common comma or dot grouping, while rejecting malformed multi-separator tokens. Repeated occurrences stay repeated; compact ranges such as 5-8 return both endpoints. Paste a message, report or list and extract the number-shaped values. For example, “Range: 5-8; change: -2.5; growth 2e3%” returns “5”, “8”, “-2.5” and “2e3”. A hyphen or plus directly between digits is treated as a separator, while a sign at a word boundary and a scientific exponent sign stay attached. Values are not converted; the tool does not infer a currency or unit, or guess whether a comma is decimal or grouping punctuation. Numbers are returned without numeric conversion. When a comma could mean a decimal mark or a thousands separator, no locale is inferred. A hyphen or plus directly between digits separates two numbers (5-8 returns 5 and 8); scientific exponent signs such as 2e-3 stay part of the number. Dates, currencies, units and ranges are not parsed as complete values; spaces used as digit grouping are not supported.

How to use it
Paste a message, report or list and extract the number-shaped values. For example, “Range: 5-8; change: -2.5; growth 2e3%” returns “5”, “8”, “-2.5” and “2e3”. A hyphen or plus directly between digits is treated as a separator, while a sign at a word boundary and a scientific exponent sign stay attached. Values are not converted; the tool does not infer a currency or unit, or guess whether a comma is decimal or grouping punctuation.
Limits
Numbers are returned without numeric conversion. When a comma could mean a decimal mark or a thousands separator, no locale is inferred. A hyphen or plus directly between digits separates two numbers (5-8 returns 5 and 8); scientific exponent signs such as 2e-3 stay part of the number. Dates, currencies, units and ranges are not parsed as complete values; spaces used as digit grouping are not supported.
Frequently asked questions
Which number formats are recognized?
Signed values, decimal points or commas, common comma or dot thousands grouping, and scientific notation are returned as written. The tool does not convert them to a numeric value.
Will it parse dates, identifiers or units?
No. It extracts number-shaped tokens, not complete dates or measurements. Malformed multi-separator tokens such as IP addresses and version strings are skipped instead of split into misleading fragments.
