This quick guide describes how to convert HTML to JSON using Node.js. It has the details to set the development environment for writing and testing the application, a list of steps to define the algorithm for the converter, and a runnable sample code to perform the task. No third-party tool or software is required to transform HTML to JSON using Node.js.

Steps to Convert HTML to JSON using Node.js

1. Set the environment to use Aspose.Cells for Node.js via Java for HTML to JSON
2. Load the source HTML file into the Workbook class object
3. Call the getLastCell() method to get the reference of the last cell on the converted sheet
4. Create a range of cells starting from the first cell to the last cell
5. Create an object of the JsonSaveOptions class
6. Call the exportRangeToJson() method to convert the specified range of cells to JSON string
7. Save the string to the JSON file

These steps define the process of developing an HTML to JSON converter using Node.js. The source HTML file is loaded into the Workbook object followed by creating a range of cells using the last cell in the created sheet. The exportRangeToJson() method is used to create a JSON string using the calculated range of cells and save it in the JSON file.

Code to Convert HTML File to JSON using Node.js

This sample code demonstrates the task of changing a file type from HTML to JSON using Node.js. The exportRangeToJson() method requires a range of cells and JSON save options using JsonSaveOptions that support defining the export area, exporting nested structure, setting indent, setting merge areas, and setting sheet index. You may use another overloaded method of the exportRangeToJson() method that requires the ExportRangeToJsonOptions class object to customize the output JSON file.
