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

Pro Tips

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