I want to read only one row each time on excel. I can read all datas in excel but I couldn't limit it. Either I can read only 1 column in all rows or the all data. How can I read just 1 row on javascript?
I use this script and this src:
<script src="https://unpkg.com/read-excel-file@4.x/bundle/read-excel-file.min.js"></script>
<body>
<input type="file" id="input">
<script>
var input = document.getElementById('input');
input.addEventListener("change", function (){
readXlsxFile(input.files[0]).then(function (data){
data.map((row,index)=>{
var location= document.createTextNode(row);
console.log(location)
If you need one row, don't map over entire file:
readXlsxFile(input.files[0]).then(data => {
console.log(data[0]) // supposed to print the first row
})
