JSON Compare Tool
Compare two JSON documents and find all differences
What is a JSON compare tool?
A JSON compare tool analyzes two JSON documents and identifies all differences between them, including missing keys, different values, type mismatches, and structural differences.
How do I compare two JSON files?
Paste your first JSON into the left input field and the second JSON into the right field, then click 'Compare JSON'. The tool will show all differences with their exact paths.
What types of differences can this tool detect?
The tool detects missing keys, different values, type mismatches, array length differences, nested object changes, and structural differences at any depth level.
Can I compare large JSON files?
Yes, the tool efficiently handles large JSON files. However, very large files (over 10MB) may take a few seconds to compare depending on your device's performance.
Does the comparison work with nested JSON?
Yes! The tool performs deep comparison, checking all nested objects and arrays at any depth level. It shows the exact path to each difference for easy identification.
Is the comparison case-sensitive?
Yes, JSON is case-sensitive, so 'Name' and 'name' are treated as different keys. The tool will flag these as differences if they appear in your JSON.
Can I compare JSON arrays?
Yes! The tool compares arrays element by element, checking both length and content. It will show which elements differ and at which index positions.
Is my data secure when comparing?
Absolutely! All comparison happens entirely in your browser using JavaScript. Your JSON data never leaves your computer, ensuring complete privacy and security.
Does the tool work offline?
Yes! Once the page is loaded, the comparison tool works completely offline. All processing happens locally in your browser without requiring an internet connection.
What happens if one JSON is invalid?
The tool will display a clear error message if either JSON is invalid, helping you identify and fix syntax errors before comparing.
