Ensure both JSON files are properly formatted and valid. You can use our JSON beautifier tool first if needed to clean up the format before comparison.
Paste your first JSON data in the left panel (JSON 1) and your second JSON data in the right panel (JSON 2). The tool supports any valid JSON structure.
Click the "Compare" button to analyze both JSON files. The tool will process the data and identify all differences between the two files.
The diff results will appear below showing side-by-side comparison with highlighted differences. Green indicates additions, red shows deletions, and yellow highlights modifications.
Green highlighting indicates properties that exist in JSON 2 but not in JSON 1. These represent new additions to your data structure.
Red highlighting shows properties that exist in JSON 1 but are missing in JSON 2. These represent deletions from your original data.
Yellow highlighting indicates properties where the key exists in both files but the values are different. This shows where data has been updated.
The tool recursively compares nested objects and arrays, showing differences at any level of depth in your JSON structure.
Array comparisons show added, removed, or modified elements. Order changes are also detected when array elements are rearranged.
Compare API responses before and after code deployments to ensure backward compatibility. Identify breaking changes in your API endpoints.
Track API evolution by comparing response schemas between different versions. Maintain documentation of API changes for your development team.
Compare configuration files between different environments (development, staging, production) to ensure consistency and identify environment-specific settings.
Verify data integrity after migrations by comparing JSON exports before and after the migration process. Ensure no data loss or corruption.
Monitor how your JSON schemas change over time. Identify when new fields are added, removed, or when data types change in your API responses.
A JSON Diff tool compares two JSON files and highlights the differences between them. It provides a side-by-side view showing additions, deletions, and modifications in your JSON data.
Paste your first JSON data in the left panel, your second JSON data in the right panel, and click "Compare". The tool will analyze both files and highlight the differences.
Yes, our JSON diff tool shows exactly what was added, removed, or modified between two JSON files with color-coded highlighting for easy identification.
Absolutely! All JSON comparison happens client-side in your browser. Your data is never sent to our servers, ensuring complete privacy and security.
Our tool supports standard JSON format. Both files should be valid JSON for accurate comparison results.
