Full C# support too

SQL not enough? Run LINQ queries against Excel tables; automate Excel using C# (instead of VBA); load data from almost anywhere using any .NET library.

You can even write C# functions and call them directly from SQL (with autocomplete too).

With C# support, Excel turns into a powerful developer tool in your arsenal.

Two-way database connectivity

Make Excel a natural extension of your databases, and vice versa.

Connecting to an external database opens a two-way connection between Excel and the database, making it easy to move data in either direction.

QueryStorm supports SQL Server, Postgres, Redshift, MySql, Oracle, SQLite, Access, and ODBC.
