CSV Table

Professionals who work with CSV and JSON files often need to filter, sort, validate and edit large datasets without writing SQL or scripts, and without exposing sensitive data to cloud services or accounts. Many existing tools require internet connectivity, telemetry, or account sign-ups, and can struggle with very large files. This creates friction for anyone who needs a fast, private way to inspect and clean tabular data, spot duplicates, empty cells or format errors, and export results without extra setup or ongoing subscriptions.

CSV Table is a native desktop app for macOS built specifically for viewing, filtering, editing and exporting CSV and JSON files. It offers a query engine with multi-condition AND/OR filters and one-click column sorting, powerful search with CONTAINS, EQUALS, GREATER THAN and regex support across millions of rows, and automatic data validation that flags type mismatches, empty cells and duplicates. Users can inline-edit any cell, batch-update columns, and rely on full undo/redo with autosave. The app supports drag-and-drop import and export of CSV, TSV and JSON files up to 10M+ rows, includes customizable themes and layout density, and runs fully offline with no account, no cloud sync and no telemetry, keeping all files and settings local to the device.
