How can I overwrite my xlsx sheet data with new data in node js

Question

Below is my code Ws -Contains redundant data while wsRemDup -contains data after removing the redundant/duplicate data. wsRemDup is an array of JSON.

I want to overwrite my ws sheets data with wsRemDup. I googled to find a way but most of the stuff showed how to append instead of overwriting it. How can I proceed?

                    ws = XLSX.utils.sheet_add_json(ws, ticketNameArr,{origin:-1, skipHeader:true});
                   //Contains unique ticket name and their other fields
                    wsRemDup=removeDuplicate(ws)
                   console.log(wsRemDup)
                    XLSX.writeFile(wb, 'DailyTicketSatus.xlsx')

                    respond.render('index', { "ticketNameArr": ticketNameArr });

You should be able to overwrite the sheet on your original workbook like so:

const excelFile = "tickets.xlsx";
const sheetName = "Sheet1" // <-- Change to the actual sheet name.
const workbook = XLSX.readFile(excelFile);
const ws = workbook.Sheets[sheetName];
let sheetJson = removeDuplicate(ws);

// Overwrite worksheet
workbook.Sheets[sheetName] = XLSX.utils.json_to_sheet(sheetJson);
XLSX.writeFile(workbook, excelFile);
