Aspose.Cells for C++ is a native C++ library designed for full‑scale spreadsheet manipulation within C++ applications. It enables developers to create, read, edit, convert, and process Excel spreadsheets without relying on Microsoft Excel or Office Automation. The library supports a wide range of spreadsheet formats—including XLS, XLSX, XLSM, XLSB, XML, OTS, ODS, CSV, TSV, JSON, HTML, MHTML, Numbers, SXC, FODS, and EPUB—as well as output formats like PDF, PDF/A, XPS, DIF, and multiple image types such as JPEG, PNG, BMP, TIFF, GIF, EMF, and SVG. Aspose.Cells for C++ supports in‑depth spreadsheet manipulation including built‑in and custom document properties, themes, styles, formatting, data validation, conditional formatting, formulas, charts, Pivot Tables, OLE objects, hyperlinks, tables, list objects, and drawing shapes. The API operates without external dependencies and is compatible with Windows, Linux, and macOS across both x86 and ARM architectures. The library includes a high‑fidelity rendering engine capable of converting charts and worksheets to images or PDF. It ensures reliable Excel‑to‑PDF conversion with precise formatting retention. Aspose.Cells for C++ simplifies Excel format inter‑conversion, allowing developers to convert files between supported formats with only a few lines of code.
