スプレッドシートデータをXLSXとして保存

7月 7, 2026
アプリケーションから直接XLSXスプレッドシートを作成し、ユーザーは互換性のあるスプレッドシートソフトウェアでデータを共有・分析可能

Exporting to XLSX in a spreadsheet component is the ability to generate Microsoft Excel Open XML Spreadsheet (.xlsx) files directly from application data or the current spreadsheet state, allowing users to save, share, and open content in Microsoft Excel and other compatible spreadsheet applications. For software developers, this provides a reliable way to deliver data in a widely supported format while preserving features such as worksheets, formulas, formatting, tables, and cell styles where supported, making it easier to integrate reporting, data exchange, and offline analysis into applications without requiring users to manually recreate or copy spreadsheet content.

Several Angular spreadsheet controls offer support exporting to XLSX including:

  • SpreadJS by MESCIUS lets you export spreadsheets to XLSX while preserving formulas, formatting, tables, and other Excel-compatible features for seamless data exchange.
  • Kendo UI Angular Excel Export (part of Kendo UI by Telerik) facilitates XLSX export from its spreadsheet component, producing Excel-compatible files that retain formatting.
  • Jspreadsheet Pro allows you to export spreadsheet content to XLSX, enabling users to share structured data with Microsoft Excel and compatible applications.
  • Infragistics Ignite UI for Angular Spreadsheet (part of Infragistics Ignite UI) lets you export spreadsheet data to XLSX, helping applications generate Excel-compatible workbooks.
