qsv vs Tableau

qsv is a CSV data-wrangling toolkit for slicing, analyzing, and transforming data through more than 50 commands. Most commands stream their input and use constant memory, so they can handle very large CSV files without loading the full dataset into memory. It works with CSV, Excel, OpenDocument Spreadsheet, JSON and JSONL, DataPackage, Apache Arrow and Parquet, SQLite, and PostgreSQL. Luau and Python scripting are built in, and the join, joinp, and sqlp commands support SQL and join queries without a SQL database. qsv is designed to interoperate with Airbyte, Airflow, Pentaho Kettle, and command-line tools. Its qsv pro desktop app adds graphical spreadsheet viewing and transformation, plus CKAN upload and download. The code is automatically checked for security vulnerabilities, and prebuilt binary archives are zipsigned with integrity checks during self-updates. qsv requires UTF-8 input. The Free plan costs nothing and includes spreadsheet imports up to 1MB; Pro costs $99.99 a month after the trial ends.
