Tad is a free, MIT-licensed desktop application for viewing and analyzing tabular data in CSV, Parquet, SQLite, and DuckDB formats. It renders fast, scrollable grids for millions of rows and provides an interactive hierarchical pivot table backed by an embedded DuckDB engine that generates SQL for pivots, filters, aggregates, and sorting.
Use cases
- quickly view a large csv file
- open and explore parquet files
- inspect sqlite or duckdb database tables
- build pivot tables from tabular data
- filter and aggregate millions of rows interactively
- copy table data into excel or google sheets
- export filtered tables as csv or parquet
When to choose
- you need a fast GUI viewer for large CSV, Parquet, or database files
- you want interactive pivot-table style exploration without writing SQL
- you are a data engineer or scientist doing quick ad-hoc data inspection
When to avoid
- you need a polished, fully supported production tool - it is a hobby project with known bugs
- you need programmatic data processing or scripting rather than interactive viewing
- you need a web-based or collaborative data analysis tool
