Compare two JSON documents

A text diff flags every reordered key and whitespace change. JSONWeave compares the data itself, so the result lists what was added, removed or changed.

Compare JSON in the workspace

How to compare JSON

Open the first document in the workspace.
Switch to Compare JSON from the command palette.
Paste or load the second document into the Modified pane.
Review the additions, removals and changes.

When a JSON diff helps

Checking what changed between two API responses after a deploy.
Reviewing a configuration change before you commit it.
Comparing an expected fixture with the actual output of a test.

Tips for a clean comparison

Format both documents first so you read them in the same layout. If one side is broken, repair it first, because the comparison works on the parsed value.
