Modern web applications often need to transform spreadsheet data into web-compatible formats for online display. One effective solution is to convert XLSX to HTML using Node.js, allowing seamless integration of XLSX content into websites or dashboards. This article demonstrates how to use a high-performance document conversion API built on a Java backend with a Node.js wrapper. This method eliminates the need for Excel software or browser plugins. The following guide outlines how to configure your environment and script the transformation process, so you can efficiently export XLSX to HTML in Node.js.

Steps to Convert XLSX to HTML using Node.js

1. Install and configure the GroupDocs.Conversion for Node.js via Java to activate XLSX to HTML conversion functionality in your environment
2. Add the groupdocs.conversion package to your project to enable access to the document conversion capabilities required for exporting XLSX files to HTML
3. Initialize a Converter object by providing the file path to your source .xlsx spreadsheet to prepare it for the conversion process
4. Instantiate the MarkupConvertOptions class and assign the target file type as MarkupFileType.Html to define HTML as the desired output format
5. Call the convert method on the Converter instance, passing the specified options, to generate and save the HTML version of the input XLSX file

To begin, apply the license to activate full functionality of the document conversion library. Next, load your .xlsx file into a Converter object, which serves as the engine for format transformation. After the file is ready, define output preferences by creating an instance of MarkupConvertOptions. Set the format type to MarkupFileType.Html, ensuring the Excel content is rendered accurately in a browser-friendly layout. Finally, use the convert method to export and save the HTML file to your local system. This straightforward process enables developers to generate HTML from XLSX in Node.js.
