Paste two JSON payloads to see a formatted view and a simple line diff—ideal for config reviews, API response checks, and debugging drift between environments.
JSON A
JSON B
A (formatted)
{
"name": "alpha",
"version": 1
}B (formatted)
{
"name": "alpha",
"version": 2
}Line-by-line diff (formatted)
Green = only in B, red = only in A, unchanged lines omitted from highlights.
It formats both JSON values and compares line by line. Very reordered keys may look noisier than a deep tree diff.
Everything runs in your browser; extremely large JSON may feel slow depending on your device.
