nu-shell-tabular-data

Read, filter, transform, and manipulate CSV/TSV files using Nushell's structured data pipeline.

Quick Start

nu -c 'open data.csv | where rating > 4.0'     # Filter CSV
nu -c 'open data.tsv -s "\t" | get column1'    # Read TSV with tab separator
open file.csv | save output.json               # Convert format

Core Data Types

• Record: { name: "John", age: 30 } — key-value pairs, access with $record.field
• List: [1, 2, 3] — ordered collection, process with each, where, reduce
• Table: List of records with the same keys — the primary data structure for pipelines
