Compare recurring CSV, TSV, or JSON exports and emit row-level change sets before syncs

Use csv-diff when an agent needs to explain what changed between two structured exports, not just that the files differ. The agent lines records up by a stable key, reports added, removed, and changed rows, and can hand the result to humans or downstream automations as readable text or machine-friendly JSON.

Prerequisites

Python 3, pip, two comparable CSV, TSV, or JSON snapshots, and a stable key column or field.

Installation

Use the upstream install or setup path that matches your environment:

• pip install csv-diff
• $ docker build -t csvdiff .
• $ docker run --rm -v $(pwd):/files csvdiff
• $ docker run --rm -v $(pwd):/files csvdiff one.csv two.csv

Requirements and caveats from upstream:

• --extra name "Python format string with {id} for variables"

• As a Python library

• You can also import the Python library into your own code like so:

Basic usage or getting-started notes:

• Consider two CSV files:

• one.csv

• id,name,age
