Columnar

Columnar opens large CSV files on a Windows desktop so users can inspect the data without relying on a heavier data-processing environment. It is designed for reviewing sizable comma-separated datasets while keeping the desktop footprint lightweight. The program presents CSV content for direct examination, making it useful when the immediate task is understanding or checking a file rather than transforming it.

It fits analysts, developers, and other Windows users who need to look through large tabular files during data checks, investigation, or routine review. Its role is focused and specific: provide a desktop viewer for comma-separated data at a scale where ordinary file inspection can become inconvenient. Columnar is published by AmitkroutTheDev.

The current release is version 0.0.1 and runs on x64 systems with Windows 8 or later, as well as Windows Server 2012 or later. It is released under an open-source license. The software’s stated platform support makes it applicable to both standard Windows desktops and supported Windows Server installations.
