Flow CSV Viewer is a light-weight tool for viewing, plotting and analyzing 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 measurement 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 plotted as line charts, and zooming, scrolling and rearranging the plots is fast and efficient, also on large data sets. Each column of the CSV file is interpreted as a variable, and the variables are listed in the left part of the screen. Moreover, each row is interpreted as a sample, and the samples are represented on the x axis of the chart area in the right part of the screen. New variables can be added by writing formulas over the existing variables. 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.
