Snapcsv provides a local‑first workflow for managing CSV files over time. It records each version of a CSV within a workspace, allowing users to track changes without relying on external services. The tool includes built‑in schema validation, so modifications that break the expected column structure are detected early.

Users can compare any two recorded releases, viewing differences at the row level. From these comparisons, Snapcsv can generate precise patch files that capture only the rows that were added, removed, or altered, enabling targeted updates and easy export of changes.

The system is aimed at individuals or teams that need lightweight, version‑controlled handling of tabular data, especially when working offline or preferring to keep data on local machines. Its experimental status indicates ongoing development, but the core functionality focuses on simple CSV versioning, validation, comparison, and patch generation.
