Vue.js 애플리케이션에서 데이터 그리드를 JSON으로 내보낼 수 있습니다

7월 24, 2025
구문 분석 및 다른 시스템과의 통합이 용이한 JSON(JavaScript Object Notation) 형식으로 표 데이터를 내보낼 수 있습니다.

Exporting a data grid to JSON format is a common feature in modern web-based data tools that involves converting the structured data displayed in a grid, such as rows and columns representing records and fields, into JavaScript Object Notation (JSON), a lightweight, text-based format commonly used for data interchange. This process enables the grid's contents to be saved in a machine-readable structure that preserves the hierarchy and attributes of the data, making it easily consumable by web services, APIs, or other applications. The benefits of exporting to JSON include its compatibility with a wide range of programming environments, ease of integration with frontend and backend systems, and suitability for transmitting data across networked systems or persisting it for later use in client-side operations or remote storage.

Several Vue.js grid controls allow you to export to JSON, including:

  • FusionGrid by FusionCharts works with Vue.js and allows you to export grid data to JSON, enabling seamless integration with APIs and JavaScript-based applications.
  • jQWidgets Grid (part of jQWidgets) offers a straightforward method to convert visible grid data to JSON in Vue.js apps, preserving data types and custom formatting.
  • Jspreadsheet Pro Data Grid (part of Jspreadsheet Pro) enables Vue.js applications to export spreadsheet-style data to JSON, ideal for syncing with databases or external services.
  • DataGridXL facilitates JSON output from grid data, ensuring compatibility with modern frameworks and smooth data handling in JavaScript-driven workflows.
