reactjsHow can I convert an XLSX file to JSON using ReactJS?

Using ReactJS to convert an XLSX file to JSON is a fairly straightforward process.

First, you'll need to install the xlsx library. This is a JavaScript library that allows you to read and write XLSX files.

npm install xlsx

Next, you'll need to create a function that takes in the XLSX file and returns a JSON object. The xlsx library provides a function called readFile that reads the XLSX file and returns a workbook object. This workbook object can then be used to convert the XLSX file to JSON.

const convertXlsxToJson = (xlsxFile) => {
  const workbook = XLSX.readFile(xlsxFile);
  const jsonData = XLSX.utils.sheet_to_json(workbook.Sheets[workbook.SheetNames[0]]);
  return jsonData;
}

The readFile function takes in the XLSX file as a parameter and returns a workbook object. The sheet_to_json function takes in the workbook object and returns a JSON object. The JSON object contains all the data from the XLSX file.

Here is an example of how to use the convertXlsxToJson function:

const xlsxFile = 'path/to/file.xlsx';
const jsonData = convertXlsxToJson(xlsxFile);
console.log(jsonData);

Output example

[
  {
    "name": "John Doe",
    "age": 25
  },
  {
    "name": "Jane Doe",
    "age": 30
  }
]
