JSON Sort Keys
Recursively sort every key in a JSON document alphabetically. Cleaner diffs, canonical configs, signature-friendly payloads. Free, browser-based.
How to use
Paste JSON — Drop in any valid JSON — config file, API response, anything.
Choose Order — Toggle ascending or descending. Indent is configurable.
Copy Output — Use the sorted JSON in PR reviews, diffs, or version control.
The JSON Sort Keys tool deterministically reorders every object key in any JSON document — recursively. Use it to build canonical configs, clean diffs, and signature-friendly payloads.
Features
Recursive deep sort — applies through nested objects.
Array order preserved (it is meaningful in JSON).
Ascending or descending option.
Configurable indent for the output.
Privacy
All processing is client-side. The tool is safe for confidential configs, environment files, and signed payloads.
Frequently asked questions
Why sort JSON keys?
Sorted keys produce deterministic output — easier to diff, easier to review in PRs, and easier to detect duplicates. Many tools (Terraform, Helm, signatures) also require canonical key order.
Does sorting break my JSON?
No. JSON object key order is officially unordered, so re-ordering keys never changes the meaning of the document.
What about arrays?
Array order is meaningful in JSON, so arrays are NOT reordered. Only object keys are sorted.
Is the data uploaded?
No — sorting runs entirely in your browser. Safe for confidential configs and tokens.
