I have two functions
- Exports HTML Table
- Download CSV file
Unfortunately my file is downloading as "Undefined" with no .csv file type.
The format seems to be fine, since the file can be opened with any text editor and can be seen to have all table data with a comma as a delimitter. Which makes it easy for Excel to take in the file and seperate each column and row.
But I need the file to download with the .csv file extension.
Here are my two functions:
function exportTableToCSV(html, filename) {
var csv = [];
var rows = document.querySelectorAll("table tr");
for(var i = 0; i < rows.length; i++){
var row = [], cols = rows[i].querySelectorAll("td, th");
for(var j = 0; j < cols.length; j++){
row.push(cols[j].innerText);
}
csv.push(row.join(","));
}
// download csv file
downloadCSV(csv.join("\n"), filename);
}
function downloadCSV(csv, filename) {
var csvFile;
var downloadLink;
csvFile = new Blob([csv], {type:"text/csv"});
downloadLink = document.createElement("a");
downloadLink.download = filename;
downloadLink.href = window.URL.createObjectURL(csvFile);
downloadLink.style.display = "none";
document.body.appendChild(downloadLink);
downloadLink.click();
}
exportTableToCSV('', 'test.csv');I believe the issue lies with 'function downloadCSV'. Any help or links to some current working examples are highly appreciated.
