Changed config field
Left JSON has retries 2 and regions eu/us. Right JSON changes retries to 3 and adds apac.
Shows removed and added JSON lines after formatting both sides.

JSON Diff
Compare two JSON values locally with optional key sorting for cleaner diffs.
At a glance: This JSON diff tool parses and normalizes two JSON inputs locally, then shows a line-level diff of the formatted result. You can sort object keys before diffing to reduce noise from key order changes in API payloads, fixtures, and config reviews.
Your input is processed locally in your browser and is not uploaded to ByteBench servers.

How to use this tool
- Paste or type your input into the tool area.
- Choose the mode or options that match your task.
- Review validation messages before copying the output.
- Use the example button when you want a known-good starting point.
Examples
Common use cases
- Compare two API responses.
- Review config changes with normalized indentation.
- Reduce false positives caused by object key order differences.
- Spot added or removed keys in JSON fixtures.
When to use this tool
Use this json diff page when you need to compare two JSON documents quickly during debugging, review, migration, or documentation work and want to keep raw input in your browser session.
If your task shifts, JSON Formatter and Text Diff Checker are usually the next useful tools.
Input and output expectations
- Expected input shape: Paste valid structured data (JSON, CSV, YAML, XML, HTML, SQL, or spec text) in the expected format.
- Typical output: Normalized output intended for review, copy, or handoff to your project files.
- Quick input example: Left JSON has retries 2 and regions eu/us. Right JSON changes retries to 3 and adds apac.
- Quick output example: Shows removed and added JSON lines after formatting both sides.
Common mistakes to avoid
- Pasting partially broken syntax and assuming the output is production-ready.
- Skipping validation messages before copying output.
- Using formatter output as a substitute for contract or integration tests.
Notes and edge cases
This tool compares normalized pretty-printed JSON. It is ideal for local inspection and quick reviews, but very large documents can still be easier to review in a dedicated file diff.
For privacy-sensitive data, keep using the tool in a trusted browser session and avoid pasting secrets into shared screens, screenshots, browser extensions, or remote support sessions.
FAQ
Does this JSON diff tool upload my input?
No. This JSON diff tool runs in your browser and does not send your input to ByteBench servers.
What input format works best in this JSON diff tool?
Use clean line-level comparison of normalized JSON input and run the example first when you want a known-good baseline. If your pasted data came from logs or docs, remove accidental wrappers before validating or converting.
How should I validate results from this JSON diff tool?
Review the status message, compare output with expected behavior, and run one quick edge-case check. ByteBench helps with utility work, but production-critical output should still be verified in your project pipeline.
