FlexCel Studio for .NET

This skill helps write C# / VB.NET / F# code that uses FlexCel — the TMS Software library for working with Excel .xlsx / .xls files, exporting to PDF / HTML / SVG / images, and generating data-driven reports from templates. Works with .NET Framework 4.6+, .NET Core / .NET 5+, .NET Standard 2.0+, .NET MAUI, Xamarin, and .NET 9 Native AOT (with caveats — see below).

When to use this skill

Activate whenever the user wants to, from .NET code:

• Read an Excel file (.xlsx or .xls) — cell values, formulas, formatting.
• Create or modify an Excel file programmatically.
• Generate reports by merging data into Excel templates.
• Export an Excel file to PDF, HTML, SVG, or images.
• Autofit rows/columns, render sheets, or measure cells.
• Target .NET Framework, .NET Core / .NET 5+, .NET MAUI, Xamarin, Blazor server, ASP.NET Core, or Native AOT.

FlexCel does not require Excel or any Office installation on the target machine. No OLE/COM, no interop. Fully managed — works on Windows, Linux, macOS, iOS, and Android.
