nSoftware Cloud Sheets is a developer kit allowing developers to provide access to cloud-based spreadsheets, such as Microsoft 365 and Google Sheets, in their own applications. Rather than having to deal with complex APIs, you obtain easy and uniform components that allow you to connect, authenticate, and manage spreadsheets with a few clicks. It is all meant to enable you to add professional spreadsheet functionality to any software that you develop in the shortest time possible.
Using nSoftware Cloud Sheets, you can create and edit your sheets, manipulate formulas, and manage data in a sheet just like you would in any other spreadsheet, except this time with your application code. The tools are not difficult to master because of the unified and intuitive design. It does not matter whether you are using Office 365 or Google; the experience remains the same, and you do not have to learn various APIs with each vendor.
The elements are highly efficient, lightweight, and designed to be liked with long-term functionality. They have secure and modern authentication (OAuth 2.0) and have native development platform libraries (FIPS-compliant cryptography). The Cloud Sheets components have decades of optimization experience, and they perform highly, consuming low resources and are stable when running demanding applications.
