Native access to Excel files. The user doesn't need to have Excel, or any other software installed. XLSReadWriteII uses it's own memory manager that is optimized for storing cell values. This means that you can work with larger files. If your files still not will fit in memory, there is a Direct Read and Direct Write modes that let you process files on disc. Stability. One of the major goals with XLSReadWriteII was to create a product that won't corrupt the Excel files and won't alter any data in the file. The engine that handles XLSX files is automatically built directly from the file format specifications with our special developed tool. This will ensure maximum comatibility.

The largest and best improvement to Delphi’s code tooling in many years, RAD Studio 10.4 provides Code Insight using a Delphi implementation of the Language Server Protocol (LSP). LSP is a technique for calculating results for code completion, navigation, or similar in a separate process. This means that the IDE will never block while completing and Code Insight will provide accurate results. 10.4 provides a much enhanced developer productivity experience when working with large projects with millions of lines of code.

Add the ultimate flexibility and power into your applications with native Pascal or Basic scripting and full IDE (Integrated Development Environment) with visual form designer, object inspector, and more.

Universal Data Access Components (UniDAC) is a library of components that provides direct access to multiple databases from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms.

Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, Delphi for .NET, C++Builder, and Lazarus (Free Pascal).
