Cómo usar: JSON Diff
- Paste the original JSON on the left and the changed JSON on the right.
- Read the summary of added, removed and changed values.
- Use the path column to locate each change; tick Ignore array order for lists whose order does not matter.
Structural diff vs text diff
A text diff compares lines, so reformatting, reordered keys or a changed indentation make every line look different. A JSON diff parses both documents and compares the data: {"a":1,"b":2} and {"b":2,"a":1} are identical, and a changed nested value is reported once with its exact path.
How changes are reported
| Type | Meaning | Example |
|---|---|---|
| added | Key or array element only in the changed document | $.license |
| removed | Key or element only in the original | $.private |
| changed | Different value or different type at the same path | $.version: "1.4.0" → "1.5.0" |
Arrays
By default arrays are compared position by position, which is right for ordered data. For sets — tags, permissions, IDs — tick Ignore array order: elements are matched by content, so only genuinely added or removed items are reported.
Typical uses
- Checking what an API change returns differently before and after a deploy.
- Comparing
package.json, Terraform state or feature-flag configs between environments. - Reviewing updates to translation files and test fixtures.
For plain-text comparison use the diff checker; to inspect one document, the JSON viewer.

Preguntas frecuentes
Does key order matter?
No. JSON objects are unordered, so the same keys and values in a different order are reported as identical.
Can I compare large JSON files?
Yes, several megabytes compare quickly in your browser. Only the first 300 characters of each changed value are shown in the table.
Is my JSON uploaded?
No. The comparison runs locally.
¿Puedo instalar JSON Diff como aplicación web y utilizarla sin conexión?
Sí. JSON Diff es una aplicación web instalable (PWA): se instala desde el navegador, no se descarga desde una tienda de aplicaciones.
