xsv is great -- as is csvkit, which preceded it and is probably a bit slower, but has a few extra utilities that I find essential: - in2csv: extracts Excel worksheets into CSV - csvsql: produces (and executes) the SQL needed to create a table and insert the data from a CSV I found these scripts to be profoundly useful when working with govt data and needing to provide a automated workflow that collects and collates their Excel spreadsheets and converts them into CSV and SQLite databases.
