Runs 100% in your browser — nothing is ever uploaded.
What is Sort JSON Keys?
Sort every object's keys alphabetically — ascending or descending, optionally recursing through nested objects and arrays. Sorted JSON produces stable git diffs, deduplicates config noise and makes large payloads much easier to scan.
How to use Sort JSON Keys
- Paste your JSON into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (delimiter, table name, format …).
- Click the convert button — the sorted JSON appears instantly in the output pane.
- Copy the result with one click or download it as a file.
ConvertLab FAQ
Is the JSON key sorter free?
Yes — 100% free, no signup, no limits, no watermarks. Use it as often as you like.
Does sorting change array order?
No — array element order is data and is always preserved. Only object keys are reordered, which never changes the meaning of the JSON.
Is my data uploaded to a server?
No. The conversion runs entirely in your browser with JavaScript — your data never leaves your device, which makes the tool safe even for confidential files.
Are these converters free?
Yes — every ConvertLab tool is 100% free with no signup, no limits and no ad walls.
Is my data uploaded anywhere?
No. All conversions (JSON, CSV, XML, YAML, INI, .env) run entirely in your browser. Nothing ever leaves your device.
Do these tools work offline?
Yes — once the page is loaded, every converter works without an internet connection.
