QueryStorm is a product from Windy Range Software that adds SQL, C#, and VB.NET programming to Microsoft Excel. The company describes it as tech-friendly spreadsheets with modern SQL and .NET programming. Users can query workbook tables, run scripts, build custom functions, and automate workbooks without leaving Excel.
The product is aimed at three groups: software engineers who want the full power of .NET in Excel, data professionals who want SQL alongside spreadsheet flexibility, and business users who use functions and workbooks that others have built. A free Community Edition exists, and paid licenses are perpetual.
For SQL, QueryStorm uses a built-in SQLite engine that runs queries against workbook tables as if they were database tables. Queries can read and update data, and any selection of cells can be accessed as a table. SQL can also find rows and cells and change their formatting, for example through the SetBackgroundColor function.
For code, users write C#, VB.NET, or SQL in the QueryStorm IDE inside Excel. That code can run as scripts or LINQ queries, become custom Excel functions, or drive the behavior of a workbook. To share the result, recipients install the QueryStorm Runtime, which does not require a license.
The core features are SQL querying, C# scripting, custom Excel functions, smart workbooks, and database integrations. Functions can be written in SQL, C#, or VB.NET and either used personally or published. Smart workbooks add business logic and interactive behavior through .NET and SQL code, and the database integrations move data between Excel and external databases.
Supporting tools include an intelligent IDE with code completion, syntax highlighting, and code fixes, plus NuGet support. The extensions gallery lists packages for text manipulation, SQL queries, currency conversion, geographic coordinates, Google Translate, and two-way sync with Monday.com, Airtable, and MailChimp. Prices for these extensions range from free to monthly subscriptions.
