JSON isn't an image
A .json file stores text data — settings, coordinates, lists — not pixels. There's no image inside to extract, and a picture can't be saved as a JSON data file.
Looking to turn a WEBP into JSON? Here's the honest answer — and the conversions that actually work.

WEBP is a modern Google format using lossy and lossless compression to make images ~25–35% smaller than JPG or PNG at similar quality, with transparency and animation support.
WEBP opens in all modern browsers and recent Photoshop, GIMP and image viewers.
No — JSON is a data format, not an image, so there's nothing to convert. You can convert your WEBP to PNG, JPG or TIFF instead.
JSON is a text-based data format used for app settings and, with a matching image, sprite-sheet coordinates. It isn't a picture.
A sprite sheet is a .png + .plist pair. Use a texture packer (TexturePacker, Cocos2d) to pack or unpack them together; a single-file converter can't.
