couldn't convert excel data to json object using convert-excel-to-json libraray
Question
I am new to node.js. i want to build a web application where it takes input a file path (excel) and converts the data to json object (takes file input from input type file). So I have taken the file path and uploaded to the directory project directory and then fed that file to convert-excel-to-json.i was expecting a json object but could not get json object. The file uploading to the project directory works fine. Can anybody help? Thanks in advance
**index.js file
const express =require("express");
const bodyParser =require("body-parser");
const excelToJson=require("convert-excel-to-json");
const upload=require("express-fileupload");
const app=express();
app.use(bodyParser.urlencoded({extended:true}));
app.use(upload());
app.get("/",function(request,response){
response.sendFile(__dirname+"/index.html");
})
app.post("/",function(request,response){
if(request.files){
let file=request.files.filesrc;
let dest=__dirname+"/"+file.name;
file.mv(dest);
const result=excelToJson({
sourceFile:dest,
})
response.send(result);
}
})
app.listen(4001,function(){
console.log("App is listening at port 4001");
})
**html file (index.html)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>
<form method="POST" action="/" enctype="multipart/form-data">
<input type="file" name="filesrc" />
<input type="submit" />
</form>
</body>
</html>
expected output : json object
my output :{"Sheet1":[]}

The convert-excel-to-json NPM package doesn't return a JSON object as they clarify in their documentation .
it returns a normal object.
If you want to convert it to a JSON object you can use JSON.stringify() to convert JS objects to the JSON object
Ex:
response.send(JSON.stringify(result));
