5月 30, 2025
ユーザーは、元のコンテンツとスタイルを保持したまま、JavaScript Webアプリケーション内で直接スプレッドシートをPDFファイルにエクスポート可能

Exporting a spreadsheet to PDF from a JavaScript application is a widely used feature that allows users to generate portable, print-ready documents directly from the browser. It converts the contents of a spreadsheet, such as cell data, formulas, formatting, charts, and images into a Portable Document Format (PDF) file. This capability ensures that the data, formatting, and layout from the original spreadsheet are preserved without relying on external applications or manual intervention. It is particularly useful for generating reports, invoices, or records that need to be shared, printed, or archived in a fixed format. By enabling PDF generation directly within the web application, developers can offer users a straightforward method to archive, print, or share spreadsheet content in a consistent and professional format across devices and platforms.

Several JavaScript spreadsheet components allow you to export to PDF, including:

  • SpreadJS by MESCIUS enables users to convert complex spreadsheet content, including formulas and styling, directly to PDF within a JavaScript application.
  • Telerik Spreadsheet jQuery (part of Kendo UI) provides an integrated PDF export option that retains the structure and styling of the spreadsheet for uniform document output.
  • Jspreadsheet Pro, through the export to PDF extension, facilitates the export of spreadsheet content to PDF, ensuring the integrity of the original document.
  • Syncfusion Spreadsheet JavaScript (part of Syncfusion Essential Studio Enterprise) allows you to save spreadsheet documents as PDF files, preserving layout and style.
