xsv is a command line program for indexing, slicing, analyzing, splitting and joining CSV files. Commands should be simple, fast and composable. Simple tasks should be easy. Performance trade offs should be exposed in the CLI interface. Composition should not come at the expense of performance. Let's say you're playing with some of the data from the Data Science Toolkit, which contains several CSV files. Maybe you're interested in the population counts of each city in the world. So grab the data and start examining it. The next thing you might want to do is get an overview of the kind of data that appears in each column. The stats command will do this for you. The xsv table command takes any CSV data and formats it into aligned columns using elastic tabstops. These commands are instantaneous because they run in time and memory proportional to the size of the slice (which means they will scale to arbitrarily large CSV data).
- Concatenate CSV files by row or by column
- Force a CSV file to have same-length records by either padding or truncating them
- Reformat CSV data with different delimiters, record terminators or quoting rules
- Build frequency tables of each column in CSV data
- Create an index for a CSV file
- Read CSV data with exotic quoting/escaping rules
