Reference & details

How it works

Text Processing Algorithm

The Extract Numbers scans input in a single pass using Unicode-aware string operations. Grapheme clusters, line breaks, and whitespace rules follow Unicode Standard Annex #29.

Pattern Matching

Regular expressions and delimiter rules identify tokens, words, sentences, or custom patterns. Case sensitivity and locale options are applied before counting or transforming.

Output Formatting

Processed text is emitted with preserved or normalized line endings as selected. Copy-to-clipboard output matches the on-screen result exactly.
