JSON Diff / Compare Tool

Compare two JSON documents and highlight the differences.

About the JSON Diff Tool

The JSON Diff tool allows you to compare two JSON documents and visually identify the differences between them. It highlights added, removed, or modified values and structures, making it easy to see what has changed.

Why Use This Tool?

Comparing JSON documents is useful for: tracking changes in API responses; verifying data transformations; debugging issues caused by unexpected data modifications; or understanding the evolution of a JSON-based configuration. This tool provides a clear, line-by-line 'git-like' diff output.

Example Use Cases

  • Comparing the response of an API before and after a code change to ensure no unintended data alterations.
  • Verifying that a data migration script correctly transformed JSON records.
  • Finding differences between two versions of a configuration file stored in JSON format.

Pro Tips

  • Format Before Diffing: For the most accurate and readable diff, it's often helpful to format both JSON inputs using a JSON Formatter before comparing. This ensures that differences are not just due to whitespace or indentation variations.
