Aspose.Cells Cloud SDK for .NET enables developers to build robust cloud-based spreadsheet processing applications using the Aspose.Cells Cloud REST API. Distributed under the MIT license, this SDK supports a rich set of features for working with Microsoft Excel (XLS, XLSX), iWork Numbers, OpenOffice spreadsheets, and many other formats—directly from .NET applications and without requiring Microsoft Excel or OpenOffice installations. With Aspose.Cells Cloud SDK for .NET, developers can create, read, merge, split, encrypt, protect, edit, and convert spreadsheets hosted in cloud storage. The SDK provides functionality for manipulating worksheets, modifying cells and ranges, working with charts, pivot tables, formulas, and running batch operations. It supports advanced data extraction, conditional formatting, auto-filtering, smart markers, and workbook protection. The SDK can be installed via NuGet, making setup fast and simple. Once cloud credentials are configured, developers can interact with Aspose.Cells Cloud using straightforward .NET code to process spreadsheets, convert workbooks, automate reporting, perform analytics tasks, and integrate spreadsheets into cloud-based workflows.
