How can I export image in Excel using Javascript?

One of my requirement is I want to export image and store inside excel using javascript.
I am using export excel using saveAs(blob, filename) and I am able to export javascript data into the excel but I could not able to export image? There is no any server side.
Any body has any idea over this

You can use xlsx library https://www.npmjs.com/package/xlsx
$("[id$=mybutton]").click(function(e) {
window.open('data:application/vnd.ms-excel,' + encodeURIComponent( $('div[id$=image]').html()));
e.preventDefault();
});

There is a JS library to create excel. I haven't tried it though. https://github.com/stephenliberty/excel-builder.js However, it should be fairly trivial to loop through your JSON and create a CSV file, which will ultimately open in excel. That might work better depending on your needs.
But to be clear, when you say store an image, do you mean a link to an image, or a base64 text of an image? The latter would be huge and probably break excel in some way.

How to write excel file with chart using js-xlsx

Using SheetJS js-xlsx "xlsx": "0.15.1" js is there a way to write excel file with chart.
Basically I want to export html page that contains chart into an excel file.
HTML page is getting exported successfully but the chart in the page is not getting displayed.
Here is the code I have used
let wb =XLSX.utils.book_new();
let element: any = document.getElementById('page1');
let ws = XLSX.utils.table_to_sheet(element);
XLSX.utils.book_append_sheet(wb,ws,'page1');

Are you using the Community build or the Pro?
As stated here, The Community build reflects the data cached in charts as worksheets. Other chart-related features, including writing and reading metadata, are included in the Pro compendium.
Remember to include your work as Chartsheet, just in case. It will continue to render it as a Worksheet if you are using the community version, but it will help us to understand the desired behavior that you are seeking.
If you provide more reference for the code, maybe we can show you some shortcuts to make it work.

Trying to export data to excel file without jquery

Im trying to export the data i have into an excel file without jquery. I've read you can use javascript but most example have jquery. The reason i don't want to use jquery is that the project is build with react.
I already have the data from the database, so i don't need to bring it again.
I want to take that data and make it into an excel file.
little bit of the code below.
<li className='col-md-3 col-height col-middle'>
<span>{fromTime}</span> //contains data
</li>
Some example use table, is it possible to export from
<div>
<li>
<span>
Would appreciate any tips, example or anything

The most common way to export data into excel would be to covert it into a csv (comma seperated values) file which can then be opened in excel.
There are plenty of tutorials on how to do this, there are many different ways with a simple google. In your case doing this in php will likely be best because your getting it from a database.

SheetJS seems perfect for this.
To export your table as an excel file use the code in this link(along with SheetJS)
Just plug in your table element's id into export_table_to_excel

How to get LanguageModel JS File?

I have been using PocketSphinx.js for speech recognition on my website. I have Downloaded language model file (.dmp). But their code uses JS file for Language model. I dont know where to get JS file. Help me out. Thanks.

As per documentation, you can convert dmp file to js and load it afterwards, see the section https://github.com/syl22-00/pocketsphinx.js/#i-embedding-the-files-into-one-large-javascript-file. Something like
$ cmake -DEMSCRIPTEN=1 -DCMAKE_TOOLCHAIN_FILE=path_to_emscripten/cmake/Modules/Platform/Emscripten.cmake -LM_BASE=/lm/dmp/folder/name -LM_FILES=model.dmp ..
Also check an alternative section https://github.com/syl22-00/pocketsphinx.js#ii-package-model-files-outside-the-main-javascript where you can do:
# python .../emscripten/tools/file_packager.py .../pocketsphinx.js/build/pocketsphinx.js --embed model.dmp --js-output=model.dmp.js
Overall, you need smaller models, big models from CMUSPHINX downloads are too large
