JSON Merge Tool

About JSON Merge Tool

This tool combines multiple JSON objects into a single object. You can choose between different merge strategies to handle nested objects and conflicts.

Merge Strategies

• Deep Merge: Recursively merges nested objects. Arrays are replaced, not concatenated.
• Shallow Merge: Only merges top-level properties. Nested objects are replaced entirely.

Conflict Resolution

When the same key exists in multiple objects, the value from the last object takes precedence (last-wins strategy).

Example: Deep Merge

Object 1:
{"user": {"name": "Alice", "age": 30}}

Object 2:
{"user": {"email": "[email protected]"}}

Result:
{"user": {"name": "Alice", "age": 30, "email": "[email protected]"}}

Example: Shallow Merge

Object 1:
{"user": {"name": "Alice", "age": 30}}

Object 2:
{"user": {"email": "[email protected]"}}

Result:
{"user": {"email": "[email protected]"}}
