Versions:
datui 0.2.52, published by derekwisong, is a command-line tool that renders large datasets into an interactive, keyboard-driven terminal interface so analysts can filter, sort, and visualize delimited files without leaving the shell. Designed for data scientists, DevOps engineers, and researchers who routinely inspect CSV, TSV, or JSON lines inside remote servers or local containers, the program loads millions of rows into memory-mapped buffers, then presents a spreadsheet-like grid with instant regex search, column-based type inference, and dynamic aggregation summaries. Because it runs entirely within the terminal, it eliminates the need to transfer files to a desktop BI suite or launch a browser-based notebook, making it practical for low-bandwidth environments, headless cloud instances, or secure air-gapped systems. Eight incremental releases since inception have added features such as frozen panes, percentile histograms, and keyboard macros, while the single statically-linked binary keeps installation footprint under 10 MB. The open-source project is catalogued in the “Data Analysis & Visualization” section, and version 0.2.52 remains the current stable build. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
