How do to upload and convert json file to excel file in using javasxript and html

I need to upload and convert JSON files like

[
    {
        "First Name": "Paul",
        "Last Name": "Craig",
        "Gender": "Male",
        "Age": 18,
        "Phone": "072-8074-38"
    },
    {
        "First Name": "Alan",
        "Last Name": "Richards",
        "Gender": "Male",
        "Age": 22,
        "Phone": "616-2480-27"
    }
]

to excel file. Before downloading the file user must be able to preview the file. This needs to be done using HTML and javascript
