DataStorm

DataStorm is a user-friendly and straightforward, cross-platform piece of software that makes it possible for you to convert files from and to JSON, XML, CSV, YML (YAML) and Plist formats.

Install the app and start converting files in no time

You can get started with this Electron-based app right away after a typical installation process. Upon launching the app, you are met by a simple main window and WYSIWYG graphical user interface.
Since there aren't any drop-down or typical menus and everything every feature right on display, taking advantage of what this app has to offer can be accomplished without any fret by all categories of users out there.

Streamlined workflow

Simply load the files using the designated button from the top part of the main window, fiddle about with some basic output settings and click the desired format.
From the app's Settings section, you can choose the location for the output directory, as well as turn the feature for overwriting files on or off.

An honest converter that could do with some extra features

The conversion process is not lightning fast but, to be fair, not slow either and, as expected, directly proportional to the number of loaded files.
This is the perfect time to point out one of the app's weaknesses, namely, the fact that it does not allow you to pause or cancel the conversion process, something that is quite annoying, especially if you have large numbers of files set up for conversion.
Additionally, on the could-be-better side of things, we must also point out that the utility does not support drag and drop, a feature that would surely come in handy when loading multiple files, from multiple sources.

Electron-based, minimalist conversion tool

All in all, DataStorm is a novice-accessible and straightforward conversion tool that helps you convert between formats such as JSON, XML, CSV, YML and Plist with no more than a few mouse clicks.
