It functions as a command-line interface for inspecting massive structured datasets while maintaining a constant memory footprint. The tool provides a text-based user interface for exploring data, featuring a custom layout engine that supports column resizing, line wrapping, and frozen headers. It includes a search mechanism to locate and visually highlight text patterns using regular expressions. Capabilities cover data manipulation through alphabetical or natural sorting and regex-driven row and column filtering. The tool also supports data extraction, allowing users to select specific rows or cells and export them to the system standard output. ## Tags ### Data & Databases - [Memory-Mapped File Access](https://awesome-repositories.com/f/data-databases/large-scale-dataset-management/memory-mapped-file-access.md) — Maps file contents directly into the virtual address space to browse massive datasets with minimal memory usage. - [Command-Line Viewers](https://awesome-repositories.com/f/data-databases/csv-file-processing/command-line-viewers.md) — Provides a memory-efficient command-line utility for inspecting and navigating large structured CSV files. - [Regex Row Filters](https://awesome-repositories.com/f/data-databases/database-schema-mapping/row-mapping-logic/row-record-access/keyword-row-filtering/regex-row-filters.md) — Filters rows by matching columns against regular expression patterns to dynamically exclude non-matching records. - [Large CSV Inspection](https://awesome-repositories.com/f/data-databases/large-csv-inspection.md) — Allows navigation of massive tabular files in the terminal without overloading system memory or crashing. - [Streaming File Reads](https://awesome-repositories.com/f/data-databases/large-file-transfer-optimizers/large-file-transfers/streaming-file-reads.md) — Reads large files in chunks on demand to maintain a constant memory footprint during navigation. - [Tabular Data Filtering](https://awesome-repositories.com/f/data-databases/tabular-data-filtering.md) — Filters and sorts tabular text files using regular expressions and exports specific row subsets. - [Data Export](https://awesome-repositories.com/f/data-databases/data-export.md) — Exports marked rows or specific selected cells to standard output for use with external analysis tools.
