Question 1

How do I compare two JSON files?

Accepted Answer

Paste the first JSON in the left textarea and the second JSON in the right textarea. Click Compare to see highlighted differences — added, removed and changed keys are color-coded.

Question 2

What types of differences are detected?

Accepted Answer

The tool detects added keys (only in second JSON), removed keys (only in first JSON), and changed values (same key but different value). All differences are color-coded green, red and yellow.

Question 3

Does the tool work with nested JSON?

Accepted Answer

Yes. The tool recursively compares nested objects and arrays, showing the full path to each difference using dot notation.

Question 4

Is my JSON data sent to a server?

Accepted Answer

No. All comparison happens entirely in your browser. Your JSON data never leaves your device.
