Large files need a different UI model

Spreadsheet apps often import a CSV into a heavy workbook model. That makes a plain text file much larger in memory and can freeze before you can inspect it.

CEESVEE keeps the data work in a Rust core and uses a virtualized grid that renders only the visible rows.

Benchmark the whole workflow

A serious large-file benchmark should include time to first visible rows, scroll smoothness, search, sort, memory behavior, and whether saving preserves the file contract.

Know when to move to data infrastructure

A CSV editor is the right inspection and focused-edit layer. If the file requires joins, repeatable transformations, complex validation, or long-running pipelines, move to scripts, a database, or dedicated data tools.
