Lottie JSON to JS Converter

Convert Lottie/BodyMovin .json animations to .js files

Why?

The After Effects plugin BodyMovin is a great way to export animations and play them on the web. These animations are exported as .json files however .json files need to be loaded from a web server, so if you're wanting to load a lottie animation on a local web page (a .html file being served from your file system) it will not work.

This app is an easy and convenient way to convert the .json file to a .js file that can be read from a local web page.

I work with a lot these animation files that are frequently changed for different animations files. I also work with a team of motion graphics designers that are not developers. This app can be provided to a member of the team who can convert the file, drop the converted file in a folder and it's good to go - no coding knowledge required.

How to Use

1. Download the app from the releases page.

2. Open the app, drag 'n' drop some .json files and click Convert. The .js files will be output in the same directory as the .json files.

3. Include the .js file that was created in the previous step in your .html file. This needs adding before configuring the lottie player with the animation. html <script src="animation.js"></script>

4. The animation is then globally available as window.animationData and can be used like this:

   lottie.loadAnimation({
     container: element,
     renderer: 'svg',
     loop: true,
     autoplay: true,
     animationData: window.animationData,
   });
