Extract Structured Data from Unstructured Text
Raw text data is everywhere: log files, CSV exports, HTML source, email headers, server outputs. The information you need is buried in that text, following a pattern you can describe but not easily pull out with basic string operations. Regular expressions give you the precision to describe those patterns, and a pattern matcher shows you exactly what gets extracted so you can validate your approach before writing code.
Our pattern matcher goes beyond simple match/no-match testing. It displays every match found in your text along with its position, length, and any capture group contents. If your pattern has named groups, those names appear in the output. If you have nested groups, the hierarchy is shown. This detailed breakdown turns regex from a black box into a transparent tool you can understand and trust.
Use it to prototype data extraction pipelines, validate parsing patterns, or troubleshoot extraction logic that is not pulling the right data. Paste a sample log file, write a pattern to extract timestamps and error codes, and see immediately whether your groups capture what you expect. When the output looks right, translate the pattern into your language of choice.
