There is one requirement in javascript to export the data (array or array of objects) to excel xlsx. I already exported the data to csv but unable to do same for xlsx. I tried many api from github so that I can used the libraries and export it to xslx but there are little help for it. I tried using stephen-hardy/xlsx.js, SheetJS/js-xlsx etc.
For exporting to csv I used this Click here! but the same cant be done for xlsx.
I tried xlsxwriter also to convert and write javascript array or array of object to xlsx but no result.
Now I m badly stuck because of the requirement. I also found out the similar post as of mine requirement Click here!
Please guys give me solution if any
A while ago, I wrote the following article, which described how to export data from a jqGrid to a "real" .xlsx file:
Export jqGrid to Excel
This basically cached the jqGrid's data into a JavaScript variable, posted it back to a server, to save into Excel. The Excel file is created using the OpenXML libraries.
This should point you in the right direction.
Alternatively, you might like to try this library:
AlaSQL
(I haven't tried this though.)
Try excelbuilderjs, I have done the same of downloading a Json Object with array of items into an excel sheet using this library.If you can please share the code on Jsfiddle, i can take a look at it and help you out

Have a question. I'm currently trying to import a single column CSV and import it into an array via Javascript. I'm quite a noob programmer so to speak, at the moment, I've tried to modify the code for what I believe works for me as per https://www.webslesson.info/2017/04/csv-file-to-html-table-using-ajax-jquery.html, however have had no success. Just looking for suggestions as to how I can approach this task.
You can use jquery-csv library for converting CSV to array
Is it possible to be able to upload an excel document with varying ranges of data, and have that data dynamically displayed in a basic form of chart(bar, pie, etc.) on our company website.
After doing some research I figured the only two possible ways to maybe do something like this is to use a very complicated macro in VBA or a Javascript parser to read the data and display it then. The data that will eventually go in here will have sensitive information so I cannot use google charts or anything like that.
This problem has to be divided into two parts.
One -part is to gather and process the information needed to display the chart.
Second - This is the easiest, a way to display a chart in HTML. For this, you can use www.c3js.org javascript library to display the chart in HTML.
Regarding part one, it depends in which technology is built your website.
For example, If it is in php, you will need to find a library in php, which can read and parse excel files.
Then you have to create a service in your website, where the data is going to be provided. For example,
www.yourcompany.com/provideChartData.php
You can format the response as json format.
Once you have solved that, you only have to call the service from your page, and the data will be dynamically displayed. You can call it using jquery library for javascript ($.post("www.yourcompany.com/provideChartData.php",function (data) { code to display chart ....}))
There is no real easy way to do this that I have found. I have had to manually parse these things in the past but there are some libraries out there for node that might help you.
https://www.npmjs.com/package/node-xlsx
You can also export form excel as CSV. When you do this, me sure to set the custom separator to something other than ',' and you should be fine to import it into a large array and get the data/charts you need.

Hope that helps.
I am still quite new to data visualization but learning quickly.
I am trying to create a small webapp in which the user can provide an excel spreadsheet and then the webapp would create a data visualization of this spreadsheet.
I have the datavisualization part working with a dataset that is just preprogrammede as a variable (array). But I would like to ask help in creating the option for the user to "upload" their own excel file and then put the data from the spreadsheet into an array variable and run the d3 datavisualization on that.
You can do it in 2 ways
Export from excel to csv
you can use a libary for PHP

so I have an IQY file (Internet Query file), it's found locally on my computer. This file when opened in excel will show me a table of a SharePoint list. I would like to use JavaScript, in IE browser (I can use ActiveXObject if needed) to search the resulted table for a value.
I already know how to search in excel, So that's not the problem. How can I turn this IQY file into an temp excel sheet with JavaScript? If it's not possible, is there a way to read from the table using the IQY file without using excel?
I hope my question is understandable.
Thank you.
So I've found a way to overcome this problem. In the file data there's an href, that when opened by a browser will display the data in excel format. So I've used this data to get the information I needed.
I´ve a Javascript object with all the data that I need to store on xls file. What could be the better way? Apache POI? Jasper-Reports? I´m not sure about the correct choice.
Thanks!
If you just need to import it with Excel I would suggest creating an CSV file out of the data instead.
This can easily be done with JavaScript and Excel can import that format.
