What Diff Two YAML Files can do:

Diff Two YAML Files makes it super easy to compare two YAML documents line-by-line. You can catch changes, removals, or additions fast without touching a terminal. It’s great for debugging configs, version changes, or YAML-based content files. Just paste your two versions and see the diff appear instantly. The output shows what was removed and added with simple, color-free symbols so you can copy or download and use it anywhere.

Example:

File A:

---
name: Alice
age: 30
city: London

File B:

---
name: Alice
age: 31
country: UK

Output:

- age: 30
- city: London
+ age: 31
+ country: UK

Common Use Cases:

Perfect when you’re comparing changes between two YAML config files, reviewing updates in a data pipeline, or debugging environment variables across dev and prod. If your workflow includes YAML, this keeps things clear and fast no setup required.

Useful Tools & Suggestions:

Before comparing files, use Prettify YAML on both so you’re not thrown off by formatting differences. And if you need to dig into specifics, Extract Keys from YAML helps you focus on just the parts that changed.
