Mac
New: Excel support and column statistics. Query .xlsx files with SQL, then press Command-I to see nulls, distinct counts and top values for any column.
SQLBlitz lets you query CSV, Excel, Parquet and JSON files with SQL. Directly, instantly, no setup required.
No database to configure. No import process. No waiting. Just open your file and start writing SQL. It's the tool that should have existed years ago.
QUERY FILES DIRECTLY WITH SQL
Other tools make you import data into a database first. SQLBlitz opens your files and lets you query them immediately. CSV, Excel, Parquet or JSON: open it and SELECT.
EXCEL FILES ARE JUST TABLES
Open .xlsx workbooks and query them like any other table. Join a spreadsheet with a CSV or Parquet file, filter and group it with SQL, and export the result to CSV.
UNDERSTAND YOUR DATA INSTANTLY
Press ⌘I to profile any column. See nulls, distinct values and the most common values, plus min, max, mean, median and standard deviation for numbers and length ranges for text. Move between columns with the arrow keys and switch tables from the dropdown.
HANDLES FILES THAT CRASH OTHER APPS
Built on DuckDB's analytical engine. Load a 500MB CSV with 2 million rows in 1.2 seconds. Get query results in 20 milliseconds. Open files that make Numbers and Excel give up.
NATIVE MAC APP
Not Electron. Not Java. A real macOS app that's fast, light, and feels like it belongs on your Mac.
