Features

Everything you need,
nothing you don't.

SQL Support

Run full SQL queries directly against your open file. Filter, aggregate, and analyze data deeply — no external tools needed.

Advanced Filtering

Filter any column by multiple values at once, including null values. Combine column filters with SQL results seamlessly.

Inline Editing

Double-click any cell to update its value directly in the table. Changes are type-aware — numbers, booleans, and nulls all handled correctly.

Flexible Export

Save your work back to .parquet or .csv. Exports respect your active filters, sort order, and SQL view.
