用內置資料驗證工具開發試算表應用程式，以防止錯誤、保持資料品質並簡化資料分析。

Data validation is a crucial feature for maintaining the integrity of data within a spreadsheet. It restricts the type of data or the values that users can enter into a cell. For example, a cell can be configured to only accept dates or numbers within a certain range. This minimizes input errors and ensures that data adheres to specified parameters, which is particularly important in scenarios where spreadsheets are used for data entry by multiple users or when the data feeds into critical business processes.

Several .NET 8 spreadsheet products offer data validation, including:

  • DevExpress Office File API (Spreadsheet Document API) is a high performance API for managing spreadsheet data in Microsoft Excel documents, supporting .NET 8 and offering data validation functionality.
  • Telerik Spread Processing (part of the Telerik UI product range) is a document processing library that supports .NET 8 and streamlines spreadsheet management, enabling data validation to ensure compliant input.
  • Infragistics WinForms Spreadsheet (part of Infragistics Ultimate UI for Windows Forms) provides data validation features to ensure data accuracy in desktop .NET 8 spreadsheet applications.
  • IronXL by Iron Software is a C# library for working with Excel files, without requiring Microsoft Office or Excel Interop, that supports .NET 8 and offers data validation for controlling data types and values in Excel files.
