nView

nView is a simple application utility for viewing, editing, searching, sorting and printing character-separated textual tabular data.
Either select "Open..." from the File menu or drag a file into the application main window list view.

The file format should be a plain text file (multiple encodings supported) and consist of lines of character-separated items. Use the Preferences window to specify CSV or TSV, or specify another other character separator. The lines should be separated by carriage returns (CR), line feeds (LF) or both (CRLF).
