YAML Merge Guide

How does YAML merging work?

Deep merge combines two YAML documents by recursively merging objects. Keys from the second document override matching keys in the first. Arrays are concatenated.

What happens with conflicting keys?

For scalar values, the second document's value wins. For objects, they are recursively merged. For arrays, they are concatenated.

Can I merge more than two files?

Merge two documents first, then merge the result with additional documents.

Is this tool free?

Yes, completely free with no signup or limits.
