Frequently Asked Questions
What is JSON Diff?
JSON Diff is a tool that compares two JSON documents and highlights the differences between them. It shows what was removed, added, or changed between versions.
Is my data secure?
Yes, all processing happens locally in your browser. Your data never leaves your device, ensuring complete privacy and security.
How does the diff output work?
Lines starting with '-' indicate items removed from JSON A. Lines starting with '+' indicate items added in JSON B. The path shows where the change occurred.
Can I compare large JSON files?
Yes, you can compare large JSON files. Since processing happens locally, there's no file size limit other than what your browser can handle.
Does the tool handle nested objects?
Yes, the tool recursively compares nested objects and shows the full path to differences, making it easy to locate changes in complex structures.
