CSView - A fast viewer for very large CSV files

Sun, 23 Oct 2016 / projects / csview

CSView is a lightweight viewer that displays the start of a data file immediately so there's no waiting around for very large files to load. Using very little memory CSView can comfortably open files larger than 4GB.

With copy and paste functionality and selectable delimiter support CSView provides a fast, clean and simple way to access very large CSV files.

Updated October 2019 - Version 1.3.4 has been updated for compatibility with macOS Catalina. There are no new features in this release.

Updated June 2019 - Version 1.3.3 has a number of bugfixes: high-DPI rendering is fixed on Windows, and CSV files with empty columns no longer cause alignment problems.

Updated April 2019 - Version 1.3 now supports searching in files, high-DPI display resolutions and has improved rendering on MacOS Mojave.


CSView is available from the Mac App Store for convenience on MacOS, but you can also download MacOS and Windows 64-bit builds below.
