📋JSON Patch Copy Operation

Duplicate values within JSON documents

RFC 6902

copy operation

What is the Copy Operation?

The copy operation duplicates the value at the "from" path to the "path" location. Unlike move, the source value remains in place. This is useful for creating backups or duplicating data.

Syntax

{ "op": "copy", "from": "/source/path", "path": "/destination/path" }

Examples

Copy Property

Duplicate a value to a new location

Patch:

{ "op": "copy", "from": "/original", "path": "/backup" }

Before:

{ "original": "data" }

After:

{ "original": "data", "backup": "data" }

Copy Nested Object

Duplicate an entire object structure

Patch:

{ "op": "copy", "from": "/template", "path": "/instances/0" }

Before:

{ "template": { "type": "default" }, "instances": [] }

After:

{ "template": { "type": "default" }, "instances": [{ "type": "default" }] }

Copy Array Element

Duplicate an item within an array

Patch:

{ "op": "copy", "from": "/items/0", "path": "/items/-" }

Before:

{ "items": ["original"] }

After:

{ "items": ["original", "original"] }

Common Use Cases

Creating backup copies before modifications
