用內置驗證工具維護可靠的試算表資料登錄，該工具可防止錯誤並保持共用活頁簿之間的資料完整性。

Data validation in spreadsheets allows users to control what information can be entered into each cell, ensuring that data remains accurate and consistent across a workbook. By defining specific rules and restrictions, it helps prevent incorrect inputs and maintains the integrity of shared data. Users can provide guidance through prompts or drop-down lists, reducing the likelihood of errors and saving time on data correction. This feature is especially valuable in collaborative settings, such as managing budgets, tracking inventory, or collecting survey responses, where reliable data entry is essential for accurate analysis and reporting.

Several ASP .NET Core spreadsheet products offer data validation, including:

  • DevExpress ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) lets you control data accuracy by defining validation rules and guiding users with clear feedback.
  • Aspose.Cells for .NET allows you to enforce consistent data entry by applying validation rules, dropdown lists, and custom error alerts.
  • Telerik ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) validates inputs, preventing errors, and maintaining consistent information across workbooks.
  • Syncfusion ASP.NET Core Spreadsheet (part of Syncfusion Essential Studio Spreadsheet Editor SDK) enables data entry through automatic prevention of invalid values.
