Why sort CSV?
Sorting helps organize data for reporting, cleanup, and import workflows.
- Better analysis: Order records by date, name, amount, or priority.
- Cleaner exports: Prepare consistently sorted files for downstream tools.
CSV parsing and sorting run entirely in your browser with no server upload; heavy output updates are deferred to keep the interface responsive on larger files.
