What problem does it solve?

Generating large Excel files in .NET applications often causes high memory consumption and performance issues when using standard in-memory spreadsheet APIs, as they load entire workbooks into RAM. This Skill solves that problem by providing access to DevExpress's low-level streaming Excel Export Library, which writes rows sequentially to produce large files with minimal memory footprint.

Core Features & Use Cases

• Streaming Excel Generation: Create .xlsx, .xls, and .csv files by writing rows sequentially, ideal for large datasets from databases or data grids.
• Full Formatting Support: Apply cell fonts, colors, borders, number formats, conditional formatting, and rich text to generated files.
• Advanced Excel Features: Add formulas, Excel tables, sparklines, pictures, print settings, AutoFilter, and data validation to streamed output.
• Cross-Framework Support: Works with both modern .NET 6+ and legacy .NET Framework 4.6.2+ projects.
• Use Case: A developer building a server-side sales report generator can use this Skill to export 100,000+ rows of sales data to a formatted Excel file without exhausting server RAM.

Quick Start

Use this Skill to generate a formatted sales report Excel file from a list of product sales data with styled headers, SUM formulas for totals, and AutoFilter enabled for easy data sorting.
