In this tutorial, we will learn how to convert JSON data to Excel format using JavaScript. Being able to convert JSON data to Excel is useful in scenarios where you want to analyze or manipulate data in a spreadsheet.

Prerequisites

To follow along with this tutorial, you will need a basic understanding of JavaScript and familiarity with JSON data.

Steps to Convert JSON to Excel

1. First, we need to retrieve the JSON data that we want to convert to Excel format. You can either fetch the data from an API endpoint or use a static JSON file. For simplicity, let’s assume we have the JSON data stored in a variable called jsonData.

2. To convert the JSON data to Excel format, we can make use of external JavaScript libraries like SheetJS. SheetJS provides various functions and utilities to work with Excel files.

3. Start by including the SheetJS library in your HTML file. You can either download the library files and link them manually, or include them from a CDN like the following:

<script src="https://unpkg.com/xlsx/dist/xlsx.full.min.js"></script>

1. Next, write a JavaScript function to convert the JSON data to Excel. Here’s an example code snippet:

function convertJSONtoExcel(jsonData) {
  // Create a new workbook
  let workbook = XLSX.utils.book_new();

  // Convert JSON to worksheet
  let worksheet = XLSX.utils.json_to_sheet(jsonData);

  // Add the worksheet to the workbook
  XLSX.utils.book_append_sheet(workbook, worksheet, "Sheet1");

  // Generate Excel file and save it
  XLSX.writeFile(workbook, "output.xlsx");
}

In this code, we create a new workbook, convert the JSON data to a worksheet using json_to_sheet function, append the worksheet to the workbook, and finally generate the Excel file using writeFile function.

1. To convert the JSON data, call the convertJSONtoExcel function, passing your JSON data as a parameter. For example:

convertJSONtoExcel(jsonData);

1. Now you can open the generated output.xlsx file and see your JSON data converted to Excel format.

That’s it! You have successfully converted JSON data to Excel format using JavaScript.

Conclusion

In this tutorial, we learned how to convert JSON data to Excel format using JavaScript. We used the SheetJS library to perform the conversion process. This can be useful when you need to analyze or manipulate data in a spreadsheet format. Remember to include error handling and handle any specific formatting requirements for your specific use case.
