Flow CSV Viewer is a light-weight tool for viewing, plotting and analyzing time series data files in CSV format. It's designed to be extremely quick and easy to use. It opens any valid CSV files immediately without any dialogs or complicated commands, and within seconds you'll be viewing and analyzing the data of interest.

Flow was originally written with the signal processing engineer in mind. It is optimized for time series data such as measurement logs and sensor data files, but it's also useful for viewing large machine learning data sets as well as for other applications where numeric data is involved. The data is visualized as line plots, and zooming, scrolling and rearranging the plots is fast and efficient, also on large data sets.

A paid version with the editing and saving capabilities, Flow CSV Editor, is also available. If you like Flow CSV Viewer, please consider supporting future development by upgrading to Flow CSV Editor.
