TableTool

TableTool provides a native graphical interface for opening and navigating CSV files on macOS. It is designed to be lightweight and fast, avoiding the overhead of Electron‑based viewers, and supports both Apple Silicon and Intel processors on macOS 10.13 or newer. Users can drag a CSV file into the window and the application will load the data within seconds, even for files up to several gigabytes in size.

The program includes built‑in filtering capabilities, allowing multiple criteria to be applied to the dataset and the filtered results to be exported quickly. It also offers a custom query feature where users can write SQL‑style statements to join several CSV files together, enabling more complex data analysis without leaving the GUI.

TableTool is aimed at anyone who needs to inspect, filter, or combine CSV data on a Mac without the latency of web‑based or heavyweight desktop tools. Its focus on speed, native performance, and simple drag‑and‑drop import makes it suitable for quick exploratory work on large tabular datasets.
