Exclude table columns while exporting it into Excel in JavaScript - javascript

I have to export my HTML table into Excel sheets. I researched a lot and found a solution. It works for me but the problem is, there is some image field in my table data and I want to remove it from table export (suppose the first column). How can I modify my code to get the desired result?
downloadVenues = () => {
var downloadLink;
var dataType = 'application/vnd.ms-excel';
var tableSelect = document.getElementById("venue-table");
var tableHTML = tableSelect.outerHTML.replace(/ /g, '%20');
// Specify file name
var filename = 'venues_data.xls';
// Create download link element
downloadLink = document.createElement("a");
document.body.appendChild(downloadLink);
if (navigator.msSaveOrOpenBlob) {
var blob = new Blob(['\ufeff', tableHTML], {
type: dataType
});
navigator.msSaveOrOpenBlob(blob, filename);
} else {
// Create a link to the file
downloadLink.href = 'data:' + dataType + ', ' + tableHTML;
// Setting the file name
downloadLink.download = filename;
//triggering the function
downloadLink.click();
}
}

Here is a way to remove all the td, tr, th or anything else with a class or id before exporting to Excel.
Set the class .remove-this to any th and td you want to remove.
function exportTableToExcel(tableID, filename = ''){
var table = document.getElementById(tableID);
var cloneTable = table.cloneNode(true);
jQuery(cloneTable).find('.remove-this').remove();
var downloadLink;
var dataType = 'application/vnd.ms-excel';
var tableSelect = cloneTable;
var tableHTML = tableSelect.outerHTML.replace(/ /g, '%20');
// Specify file name
filename = filename?filename+'.xls':'excel_data.xls';
// Create download link element
downloadLink = document.createElement("a");
document.body.appendChild(downloadLink);
if(navigator.msSaveOrOpenBlob){
var blob = new Blob(['\ufeff', tableHTML], {
type: dataType
});
navigator.msSaveOrOpenBlob( blob, filename);
}else{
// Create a link to the file
downloadLink.href = 'data:' + dataType + ', ' + tableHTML;
// Setting the file name
downloadLink.download = filename;
//triggering the function
downloadLink.click();
}
}

i want to save chart html to word file as image
but word file can download but chart image is just X image it means doesn't have data
could you give me solution
function ExportToDoc(filename = "") {
html2canvas(document.getElementById("pyramid")).then((canvas) => {
canvas.toBlob((blob) => {
if (blob) {
myBlob = blob;
}
});
});
var HtmlHead =
"<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:w='urn:schemas-microsoft-com:office:word' xmlns='http://www.w3.org/TR/REC-html40'><head><meta charset='utf-8'><title>Export HTML To Doc</title></head><body>";
var EndHtml = "</body></html>";
//complete html
// var html = HtmlHead + document.getElementById("pyramid").innerHTML + EndHtml;
var html =
HtmlHead +
"<img src='" +
URL.createObjectURL(
new Blob(new Uint8Array(myBlob), { type: "image/png" })
) +
"'/>" +
EndHtml;
// "<div id='export'><img class='hide' src='" + URLObj.createObjectURL() +"'/></div>"
//specify the type
var blob = new Blob(["\ufeff", html], {
type: "application/msword",
});
// Specify link url
var url =
"data:application/vnd.ms-word;charset=utf-8," + encodeURIComponent(html);
// Specify file name
filename = filename ? filename + ".doc" : "document.doc";
// Create download link element
var downloadLink = document.createElement("a");
document.body.appendChild(downloadLink);
if (navigator.msSaveOrOpenBlob) {
navigator.msSaveOrOpenBlob(blob, filename);
} else {
downloadLink.href = url;
downloadLink.download = filename;
downloadLink.click();
}
document.body.removeChild(downloadLink);
}
enter image description here
for HTML
<Chart
id="pyramid"
...
</Chart>
chart is working well
function ExportToDoc(filename = "") {
var img = new Image();
html2canvas(document.getElementById("pyramid")).then((canvas) => {
img.src = canvas.toDataURL();
var HtmlHead =
"<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:w='urn:schemas-microsoft-com:office:word' xmlns='http://www.w3.org/TR/REC-html40'><head><meta charset='utf-8'><title>Export HTML To Doc</title></head><body>";
var EndHtml = "</body></html>";
var html =
HtmlHead + "<img class='hide' src='" + img.src + "'/>" + EndHtml;
var blob = new Blob(["\ufeff", html], {
type: "application/msword",
});
var url =
"data:application/vnd.ms-word;charset=utf-8," +
encodeURIComponent(html);
filename = filename ? filename + ".doc" : "Document.doc";
var downloadLink = document.createElement("a");
document.body.appendChild(downloadLink);
if (navigator.msSaveOrOpenBlob) {
navigator.msSaveOrOpenBlob(blob, filename);
} else {
downloadLink.href = url;
downloadLink.download = filename;
downloadLink.click();
}
document.body.removeChild(downloadLink);
});
}
I solved it by myself.
Also upgraded:
function htmlToFile(element, file = "hwp") {
var img = new Image();
html2canvas(document.getElementById("pyramid")).then((canvas) => {
img.src = canvas.toDataURL();
var header = "<html><head><meta charset='utf-8'></head><body>";
var footer = "</body></html>";
var sourceHTML =
header + "<img class='hide' src='" + img.src + "'/>" + footer;
var source =
"data:application/vnd.ms-word;charset=utf-8," +
encodeURIComponent(sourceHTML);
var fileDownload = document.createElement("a");
document.body.appendChild(fileDownload);
fileDownload.href = source;
fileDownload.download = "Document." + file;
fileDownload.click();
document.body.removeChild(fileDownload);
});
}

How to force dataTableToCsv method in Google Visualization API to escape the hashtag sign

It looks like the dataTableToCsv method stops when it encounters a "#"
Because this is a google defined method, what would be the best way to escape this sign or even better, correct this?
csvContent = csvColumns + google.visualization.dataTableToCsv(data);
Here's a test. Notice that in this example, it will stop at Column D second row.
google.charts.load('current', {
callback: drawBasic,
packages: ['table']
});
function drawBasic() {
var query = new google.visualization.Query(
'https://docs.google.com/spreadsheets/d/1w1vaFAPTE440jc2cpYGftXSaPwGxU_x7iQRSGK35oYc/edit#gid=0'
);
query.setQuery('SELECT *');
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
return;
}
var data = response.getDataTable();
var options = {
title: 'test'
}
var chart = new google.visualization.Table(document.getElementById('chart_div'));
chart.draw(data, options)
$('#Export').on('click', function () {
var csvColumns;
var csvContent;
var downloadLink;
var fileName;
// build column headings
csvColumns = '';
for (var i = 0; i < data.getNumberOfColumns(); i++) {
csvColumns += data.getColumnLabel(i);
if (i < (data.getNumberOfColumns() - 1)) {
csvColumns += ',';
}
}
csvColumns += '\n';
// build data rows
csvContent = csvColumns + google.visualization.dataTableToCsv(data);
// download file
fileName = 'data.csv';
downloadLink = document.createElement('a');
downloadLink.href = 'data:text/csv;charset=utf-8,' + encodeURI(csvContent);
downloadLink.download = fileName;
raiseEvent(downloadLink, 'click');
downloadLink = null;
function raiseEvent(element, eventType) {
var eventRaised;
if (document.createEvent) {
eventRaised = document.createEvent('MouseEvents');
eventRaised.initEvent(eventType, true, false);
element.dispatchEvent(eventRaised);
} else if (document.createEventObject) {
eventRaised = document.createEventObject();
element.fireEvent('on' + eventType, eventRaised);
}
}
});
}

You want to download the values of Spreadsheet as a CSV file.
In your current issue, the CSV data is not completed. It's "it will stop at Column D second row".
If my understanding is correct, how about this modification? Please think of this as just one of several answers.
It was found that when I saw csvContent of csvContent = csvColumns + google.visualization.dataTableToCsv(data);, the CSV data has the whole values from the Spreadsheet. So in this modification, csvContent is converted to a blob and it is downloaded.
Modified script:
When your script is modified, please modify as follows.
From:
downloadLink.href = 'data:text/csv;charset=utf-8,' + encodeURI(csvContent);
To:
downloadLink.href = URL.createObjectURL(new Blob([csvContent], {type: "text/csv"}));
or
downloadLink.href = window.URL.createObjectURL(new Blob([csvContent], {type: "text/csv"}));
References:
Blob
URL.createObjectURL()
If I misunderstood your question and this was not the direction you want, I apologize.

Html tables within div export to excel

Need to export div tables to excel. The above code works fine in Chrome but not working in IE. Can anyone help me out on the same.
In IE a dynamically created anchor tag needs to be added to the DOM to execute its click event. Furthermore the download attribute is not supported in the IE:
Download attribute on A tag not working in IE
Edit:
Recently I posted many answers handling this issue, here are two of those:
image does not download with it's own extension
JS Base64 string to downloadable pdf - Edge
Basically you have to use msSaveOrOpenBlob() in IE:
var tF = 'Whatever.xls';
var tB = new Blob(..);
if(window.top.navigator.msSaveOrOpenBlob){
//Store Blob in IE
window.top.navigator.msSaveOrOpenBlob(tB, tF)
}
else{
//Store Blob in others
var tA = document.body.appendChild(document.createElement('a'));
tA.href = URL.createObjectURL(tB);
tA.download = tF;
tA.style.display = 'none';
tA.click();
tA.parentNode.removeChild(tA)
}
In the case above:
var tT = new XMLSerializer().serializeToString(document.querySelector('table')); //Serialised table
var tF = 'Whatever.xls'; //Filename
var tB = new Blob([tT]); //Blob
if(window.top.navigator.msSaveOrOpenBlob){
//Store Blob in IE
window.top.navigator.msSaveOrOpenBlob(tB, tF)
}
else{
//Store Blob in others
var tA = document.body.appendChild(document.createElement('a'));
tA.href = URL.createObjectURL(tB);
tA.download = tF;
tA.style.display = 'none';
tA.click();
tA.parentNode.removeChild(tA)
}

Could Someone help me?
var csvContent = "data:text/csv;charset=utf-8,";
// Iterating through all the objects
data.forEach(function (infoArray, index) {
// Fetching all keys of a single object
var _keys = Object.keys(infoArray);
var dataString = [];
[].forEach.call(_keys, function(inst, i){
dataString.push(infoArray[inst]);
});
dataString = dataString.join(";");
csvContent += index < data.length ? dataString + "\n" : dataString;
});
var encodedUri = encodeURI(csvContent);window.open(encodedUri);
var encodedUri = encodeURI(csvContent);
var link = document.createElement("a");
link.setAttribute("href", encodedUri);
link.setAttribute("download", "my_data.csv");
