csvsv v0.0.10

csvsv

Command-line tool that enables querying of CSV data using vanilla JS

Outline of usage

Scenario: You have a large CSV file, and you want to do a somewhat-complex query against it - a grep won't cut it.

Run csvsv init --with-docs. A query.mjs file will be created, filled with advice on how to populate it to suit your needs.

Run csvsv run. A new directory will be created with outputs to match your query.mjs file.

For a full breakdown of supported functionality, run csvsv -h

Features

• Apply filters to the CSV - include/exclude just the rows you care about
• Extract & transform the data - create new CSV rows from old, using plain old Javascript
• Aggregate - import simple functions to aggregate over rows. For instance, use this to find counts, totals, or generate lists of unique identifiers
