my json file reads differently than yours did.

I didn't download the files, i created my own on my laptop and followed along. but I copied the posts.json files inside the mock file just like it read on the tutorial( i left some of the long string out to save time). After I update the server, and go the the localhost/blog it reads the file fine like it should. But in the video yours looks nicer, cleaner, has color and bold headers and spaced and indented. Mine does not. Mine just read like a Json file does straight, black and white, single spaced from word to word, character to character, not indenting, not colors, just one plain json paragraph. is this how it should be lookiing?
