JSON Compare

JSON Compare lets you compare two JSON documents and quickly find the differences between them. You can add the original and updated JSON by pasting the text directly into the input fields or by selecting .json files from your device. You can also combine both methods, such as pasting one JSON document and loading the other from a file.

After adding both documents, click Compare JSON to start the comparison. The tool opens a Comparison Results section showing the number of added, removed and modified values, together with the total number of changes.

For example, you can compare:

Original JSON

{
  "name": "CodeLiqo",
  "version": 1,
  "city": "Madrid"
}

Updated JSON

{
  "name": "CodeLiqo",
  "version": 2,
  "language": "English"
}

In this example, version has been modified, city has been removed and language has been added. The comparison results make these changes easy to identify without manually checking both documents.

JSON Compare is useful for comparing API responses, configuration files, application data and different versions of JSON files. The results also show the JSON path and the relevant values for each detected change, which makes it easier to locate differences inside larger documents.

If both documents are identical, the tool indicates that no changes were found. JSON Compare processes your data locally in your browser, so your JSON is not uploaded to a server.
