Frequently Asked Questions
JSON diffing is the process of comparing two JSON objects to identify the differences between them. This is useful for debugging, reviewing changes, or understanding data modifications.
The side-by-side view shows the original JSON on the left and the modified JSON on the right. Added content is highlighted in green on the right, while removed content is highlighted in red on the left.
Pretty format adds indentation and line breaks to make the JSON more readable. Compact format removes all whitespace to make the JSON more condensed. Both formats are valid JSON, just displayed differently.
Yes, the tool can handle large JSON files. However, for better performance, we recommend splitting very large files into smaller chunks or focusing on specific sections you want to compare.
Common JSON validation errors include missing quotes around property names, trailing commas, or using single quotes instead of double quotes. The tool will show an error message to help you identify and fix these issues.
