How it works

Paste your content or open a supported local file.
Choose your settings, then preview or process it.
Copy or download the result. Clear your work when finished.

A few useful details

Object key order is ignored. Arrays are compared by position. Changes use JSON Pointer paths; this is a structural comparison, not a semantic merge.

Inputs are limited to 1 MB; text comparison is limited to 100,000 characters per side. File contents are not saved between visits.

A PRACTICAL GUIDE

When to use JSON comparison

Review API responses and configuration changes without differences caused only by indentation or object-key order. The result identifies added, removed and changed values using JSON Pointer paths. Both documents need valid standard JSON.

A changed API field

Original: {"name":"FilePebble","version":1}
Updated:  {"version":2,"name":"FilePebble"}

Changed path: /version

Reordering the object keys does not create a change. Updating the version does.

Frequently asked questions

Does array order matter?

Yes. Arrays are compared by position, so reordering items can create differences even when the same values remain.

Can I compare very large integer IDs?

This tool parses numbers with JavaScript precision. Quote IDs beyond the safe-integer range as strings on both sides. The separate JSON formatter preserves original number spelling; this structural comparator does not.

What does /items/0/name mean?

It points to the name field in the first item of the items array. JSON Pointer escapes a slash in a key as ~1 and a tilde as ~0.
