Answer 1

import xlsx2json from 'xlsx2json';
OR
const xlsx2json = require('xlsx2json');
const excel2json = [
(req, res, next) => {
xlsx2json(req.body.file.path)
.then(result => result[0])
.reduce((object, item, index) => {
if (index === 0) {
object.mapper = item; // eslint-disable-line no-param-reassign
return object;
}
const data = {};
Object.keys(item).forEach((key) => {
data[object.mapper[key]] = item[key];
});
object.data.push(data);
return object;
}, { mapper: {}, data: [] })
.then(excel => console.log(excel)) // this gives json as output
.catch(err => next(err));
},
];

npm install xlsx-to-json-lc --save
npm install xls-to-json-lc --save
var exceltojson = require("xls-to-json-lc");
exceltojson({
input: "pass the input excel file here (.xls format)"
output: "if you want output to be stored in a file"
sheet: "sheetname", // specific sheetname inside excel file (if you have multiple sheets)
lowerCaseHeaders:true //to convert all excel headers to lowr case in json
}, function(err, result) {
if(err) {
console.error(err);
} else {
console.log(result);
//result will contain the overted json data
}
});
