JSON inputs

Objects are compared by key. Arrays are compared by position, so changed order can create differences.

How to Compare JSON Safely

What this tool checks

Object keys

Object members are matched by key, so formatting and key order do not count as changes.

Array items

Arrays are matched by index. If an item moves, the tool reports the positions that changed.

Value types

A number, string, boolean, null, object, and array are treated as different JSON types.

Common mistakes

Using JavaScript object syntax

JSON needs double-quoted property names and string values. Single quotes and trailing commas will not parse as JSON.

Expecting object order to matter

JSON objects are unordered. Reordering keys is usually formatting, not a data change.

Comparing reordered arrays

Array order is meaningful. Sort arrays first if the order should not matter for your use case.

Tips

Compare small samples first

For large API responses, compare the smallest object that shows the problem before pasting the full payload.

Copy the patch

Use the patch output when you need a compact list of add, remove, and replace operations.

Keep private data out

The comparison runs in your browser, but you should still remove secrets before saving a local history entry.
