# 1 Pretty Print json
```toml
[package]
name = "s1"
version = "0.1.0"
edition = "2021"

[dependencies]
serde_json = "1.0.128"
```
This is no robustness: we're `unpack`ing everything.
```rust
use serde_json;

fn main() {
    let json = std::fs::read_to_string("example.json").unwrap();
    let data: serde_json::Value = serde_json::from_str(json.as_str()).unwrap();
    let pretty = serde_json::to_string_pretty(&data).unwrap();
    println!("{}",pretty);
}
```
