How to use JSON Diff

Compare two JSON values by path instead of noisy text formatting.

1. Paste, type, or drag and drop a supported text file into the input area.
2. Place the second value in the adjacent panel. Sensitive fields are masked by default.
3. Review the input and the clearly labeled output behavior.
4. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

Use “Swap inputs” to reverse the comparison without copying either value.

What the result means

Added, removed, and changed paths with their values.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

• Array items are compared by index; the tool does not infer moved records.
