CSVFileView is a simple freeware tool which enables you to view and convert CSV files, even if you don't have a full-strength spreadsheet around.
The program can open CSV or tab-delimited files, optionally automatically detecting the delimiter and quote characters, and loading some or all of the lines.
The file is displayed in a table, where you're able to sort, rearrange or hide columns as required.
The program can save your data as a tab or comma-delimited file, an HTML report, or in XML and JSON formats.
Advanced features include filters, giving you more detailed control over the data you'd like to view, and a command-line interface for automating file conversions and other tasks.
A simple but effective CSV viewer with one or two surprising extras (check out the SQL WHERE-like filters).
