Frequently Asked Questions
What is a JSON diff?▾
A JSON diff shows the differences between two JSON objects or files. It highlights which keys were added (shown in green), which were removed (shown in red), and which values were changed (shown in yellow). It is useful for comparing API responses, config files, or data migrations.
How do I compare two JSON files?▾
Paste the first JSON in the left panel and the second JSON in the right panel, then click Compare. The diff view shows all changes between the two JSONs, including nested differences.
Is JSON diff case-sensitive?▾
Yes. JSON keys and string values are case-sensitive. 'Name' and 'name' are considered different keys. 'Alice' and 'alice' are different values.
