ECSV is a simple database file. ECSV files can be opened and edited using any text editor, for example, Windows Notepad. The most comfortable way to view ECSV files is to use a spreadsheet document viewer, such as Microsoft Office Excel.

ECSV files store data organized in rows and columns, with each entry (value) separated by a comma character. ECSV files typically store PCS data and technical or engineering information.
