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

I'm getting a it confused here. In a VueJS project I'm using a dummy json data in the following way :
import data from './assets/data.json'
which i can than print to the screen, for example : {{Object.keys(data)}}
In this
question i find different answers, some claim you cant import json files, some claim you can
. common sense implies that i can import them since it is working in my project, now the question is:
is this some Webpack magic helping me to achieve this import or any other behavior taking place under the hood? or is ES6 actually allows me to import json as presented above?
Please go through,
How to import a json file in ecmascript 6?
Says,
ES6/ES2015 doesn't support loading JSON via the module import syntax
Intro
Hi, I was looking for answer in the whole Internet (in some way I kind of feel that I know every question in Stack Overflow), but the answers were never appropriate to what I'm looking for. I was trying to avoid posting question here, but situation forced me to do this.
Sorry if the answer is simpler than I think.
I'm in the middle of building my first app in Electron using JavaScript. I think that I should describe it in few words, so flam:ngo™ (which is projects name) should work like this:
User will upload two files:
file with tables (like XLSX or DOC)
file with data and blank spaces (which will be used as a template)
App will import from tables.
Now app should let user choose which rows he's interested in and where in uploaded file he wants them to be placed.
flam:ngo save document in PDF (or DOC).
Clue
Right now I need solutions just for myself and in little simpler form. For now I need flam:ngo just to work with one specify XLSX and with one DOC template, but I stuck. I know which rows in document I will always need, but I don't know what should I write to specify in JS's code that I need exactly this ones (like hey, app, pick only this one, this one and maybe this one) while JS is reading file and I don't know how to create new DOC (or PDF) file, how to write data in specified blank spaces and then at the end: how to save it in direction which I should choose for every time I'm using an app - everything in one, maybe two, processes.
Ending
Could you, please, help me: for now I have implemented file uploader which is importing file in XLSX and which is saving it as CSV, XML oraz HTML. What should I do to keep moving forward?
I really appreciate your help!
PS. For better explanation:
For now this should look like this:
1. "template.docx" is uploaded in the core
2. user uploads .xlsx
3. app reads tables and select rows chosen in code
4. app puts data from chosen rows in specify places
5. app saves file > new life of the app :)
Ok, so it's been a while and app has been already written by me. Maybe this will help someone in the future:
Solution
Packages that helps me with this issue was:
js-xlsx which converts my file to simple HTML file, where cells from my XLSX template file have always the same ID (which was important for me to work with document templates).
officegen which helps me write brand new document based on earlier prepared template.
Rest of it was just Vanilla JS.
I have a plunker attached herewith.

I am able to import a text file properly without any errors. However, when I try to import an Excel file, it imports random alphanumeric values and unrelated data.
Can you please let me know if there is an easy way out there to import and Excel file (csv and xlsx file )?
I read online and found this document but I am not sure how it is used in JavaScript and HTML. Can anyone help?

You may use js-xlsx library to parse excel file to json using javascript
js-xlsx
the readme file explain how to use the library, or you may refer to the following article which talks about the library usage
Parse and Read Excel Files (xls/xlsx) With JavaScript
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

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.
