Problems with formatting data coming from the html table to the xlsx file in filesaver.js - VueJs - vue.js

Question

I'm using the Filesaver.js library to export an .xlsx file from a table I own. But I am getting some errors. See below:
Original table created using VueJs with Quasar Framework:
Generated .xlsx file:
Another case
Generated .xlsx file:
My code:
exportTable() {
let wb = XLSX.utils.table_to_book(document.querySelector('.q-table'), {
sheet: "Sheet JS",
})
let wbout = XLSX.write(wb, {
bookType: 'xlsx',
bookSST: true,
type: 'binary'
})
function s2ab(s) {
let buf = new ArrayBuffer(s.length)
let view = new Uint8Array(buf)
for (let i = 0; i < s.length; i++) view[i] = s.charCodeAt(i) & 0xFF
return buf
}
saveAs(new Blob([s2ab(wbout)], {
type: "text/plain;charset=utf-8"
}), 'test.xlsx')
Why is the format of the characters in the table not being kept when exporting the spreadsheet ?
Is my spreadsheet data not treated as a string?

After a few days of looking for answers, I managed to solve my problem.
More precisely, just use {raw: true}. By doing this, the lib no longer formats the data, leaving it in the raw form that comes from HTML. Interestingly, I didn't find this in the documentation.
// import something here
import Vue from 'vue'
import XLSX from 'xlsx'
import {
saveAs
} from 'file-saver'
// Global Function
const exportExcel = (table) => {
let wb = XLSX.utils.table_to_book(table, {
sheet: "Sheet JS",
raw: true // Here
})
let wbout = XLSX.write(wb, {
bookType: 'xlsx',
bookSST: true,
type: 'binary'
})
function s2ab(s) {
let buf = new ArrayBuffer(s.length)
let view = new Uint8Array(buf)
for (let i = 0; i != s.length; i++) view[i] = s.charCodeAt(i) & 0xFF
return buf
}
saveAs(new Blob([s2ab(wbout)], {
type: "text/plain;charset=utf-8"
}), 'spreadsheet.xlsx')
}
Vue.prototype.$exportExcel = exportExcel;
// "async" is optional;
// more info on params: https://quasar.dev/quasar-cli/cli-documentation/boot-files#Anatomy-of-a-boot-file
//export default exportExcel
