# Comparing

Two documents, compared by what they mean rather than by line order.

## Across the two shapes

A verb is implemented once per shape, not once per format. That is why a CSV gets the same tools as a webhook payload: both collapse to one of two shapes before any verb runs.

How the shapes differ for diff: Document: path-level · Records: keyed.

- document · JSON, YAML, XML
- records · NDJSON, CSV, TSV, Markdown table, Log
