About this tool

Filters lines of text based on user-defined criteria, allowing users to process large blocks of textual data efficiently. The tool accepts multi-line input and processes each line individually against a specific rule set or pattern. Users can define what constitutes an inclusion criterion—such as containing certain keywords, matching a specific format, or meeting another programmed condition—and the software automatically outputs only those lines that satisfy the defined parameters. Individuals who work with structured text data, such as log files, scraped content, or delimited lists, find this utility particularly useful. It helps users quickly refine massive datasets by isolating relevant information and discarding noise.
