Contributing To discuss a new feature or ask a question, open an issue.Working with CSV data is a common business case, and although a mobile device and screen is not the perfect view for a table, we can still work with the data in an acceptable way!

In this tutorial we will import a CSV file into our Ionic app using the papa parse library or better, the Angular wrapper around it! We will parse the raw CSV data into objects that we can work with, present it in a table where we can edit all data and finally also build the export functionality for both web and mobile! In order to build the functionality we start with a blank app and install papa parse, plus two more Cordova plugins:. Now finally we need some data to test. We assume a standard format, but if you have a different delimiter or any other non standard stuff you can look up the options you need to specify in the papa parse documentation easily.

First of all, we need to load the file which is stored locally in our case. If your app is on a server, the procedure would actually be the same just with a different URL. Once you then got the data, you can easily parse it with papa parse into an array with all your data. Inspect the array data and you can see that we can splice the item at the first position as our header row and use the rest as the real data information.

To export the data we can call unparse which is basically the opposite direction. This will create a new CSV file from our array data that we can then write to a local file in our apps data directory. With this plugin you can share or save the file basically wherever you want — give it a try and inspect the location after you shared it!

Also, our trackByFn function is used to track changes to our element s. Our view for the CSV data basically consists of a table with rows and columns that we use inside the ngFor iteration on our data.

Here we make use of the before mentioned function to track the changes of the elements in the view! To finally get something we can use on a mobile device we will give the table a bigger width through CSS next, and to make our screen scroll horizontal we can set the scrollX attribute on the ion-content of the view!

This is basically the replacement for using ion-scroll in previous versions. Finally we add a bit of CSS so the view looks nice on a mobile device and we can always see which cell we are editing by using the has-focus class that is automatically added to an input once we touch it!

Now your CSV worker app is ready, working both inside a desktop browser and deployed as a native application! The tricky part is as always working with files, but these issues can also be addressed with the right packages! Share For native file creation. For moving the file to e. HttpClientModule.

I know how to do it it's not hard, but it uses a modern web API and it could potentially be a valuable addition to the library. I think it's an awesome feature, though, and would support including it with that caveat noted. I used this for a project at my last work.

If there's no objection, I'll be happy to build it into 4. Yes please! Awesome library. But yeah, really hard to find any clear documentation on how to get the Papa. Looks like this didn't go anywhere, but it would be awesome if it did land in a new version. I'll use your snippet in the meantime, mholt - thanks!

I haven't abandoned this -- still on my list for the next version, along with a million other little fixes. Just been busy with another project the last few months. Gotta encrypt the Web!! This is a great discussion!! This helped me a lot. Thanks everyone who contributed to this thread. I want to, but right now this project is being squeezed out by another project of mine that has funding. Gotta pay the bills, you know. If somebody is willing to fund the development of this project then I will be able to afford to put time into it sooner!

Unfortunately, none of these solutions work in Safari 9. I just tested them all, and they all still open raw text in a new browser tab and do not download. If you use dispatchEvent of a new MouseEvent click, instead.

The only browser i have problem to get working is Safati. I don't have any idea about the way to make it work there. Then it had options of dispaying as a table and downloading a file. The original all-JS solution had to be dropped because it didn't show consistent results across browsers what my customers insisted on. I ended up using a sub-form that will drop that content to a tiny PHP script, that will just stick a proper header and return right back.

Banging my head against same issue with Safari 9. Doesn't seem to work in Safari Safari's fault I thinkbut I used it in my project with the proviso of limited browser support it's a utility for a small group with specific needs. Works for Safari Version With the multiple solutions posted here, have anybody tried downloading a large file?

Due to security concerns this file access is bound to files that have been opened manually by the user though. That means it is not yet possible to simply read arbitrary files from a folder. Papa Parse will deduce itself what separator was used — in case its heuristics fail you can help out with delimiter : ";". Otherwise all fields would be typed as strings. It even allows you to have a file read within a separate thread to keep your web application from freezing for a while.

A succinct documentation on further features — like error handling f. This is an awesome tutorial! Do you have a submit button somewhere that calls these functions? I experienced a similar issue in Chrome, and I think what may have happened is that the script was run, and then the user opened up the console.

When I loaded the page, then opened the console, then ran the script using a different user, I did not experience the issue. There should be no reason why you would have to load a file twice — either it works the first time or never.
