A JSON sorter reorders the keys in a JSON object alphabetically so your data is consistently structured and easy to scan. Sorted JSON produces cleaner diffs in version control, makes large configs easier to navigate, and helps teams maintain predictable key ordering across projects — all without writing a line of code.

How to Sort JSON Keys
JSON objects are technically unordered by the specification, but the order keys appear in a file matters for humans: it affects readability, makes diffs noisier, and creates inconsistencies between developers. A JSON key sorter brings order to that chaos by normalizing every object's keys into a predictable alphabetical sequence.
Step 1: Paste Your JSON
Copy the JSON you want to sort — from an API response, a config file, a database export, or any other source — and paste it into the input textarea on the left. The tool accepts any valid JSON including deeply nested objects and mixed arrays.
Step 2: Configure Sort Options
Choose your sort direction (A→Z or Z→A), indentation preference (2 spaces, 4 spaces, or tab), and whether to sort nested objects. If you check Sort Nested Objects, the sorter recurses into every nested object at every depth level. If you uncheck Preserve Array Order, arrays containing only primitive values will also be sorted.
Step 3: Sort and Review
Click Sort Keys to produce formatted output with keys in alphabetical order. Use Sort + Minify if you need a compact single-line result for environment variables or configuration strings. Any JSON parse errors will be reported with position info so you can fix them before sorting.
Step 4: Copy or Download
Click Copy to put the sorted JSON on your clipboard, or Download to
save it as a .json file. All processing
happens locally in your browser — your data is never sent to any server.
FAQ
Is this JSON sorter free to use?
Yes, completely free. There are no usage limits, no premium tiers, and no account required. Sort as much JSON as you need.
Is my JSON data kept private?
Absolutely. All sorting happens entirely in your browser using client-side JavaScript. Your JSON data is never sent to any server, never stored, and never logged.
What does sorting JSON keys mean?
Sorting JSON keys means reordering the property names within JSON objects alphabetically (A-Z or Z-A). This is useful for normalizing JSON structure, making diffs more readable, and making large JSON objects easier to scan visually.
Does it sort nested objects too?
Yes, when Sort Nested Objects is enabled, the sorter recurses into all nested objects at every depth level and sorts their keys as well. This ensures consistent ordering throughout the entire JSON document.
What happens to arrays when I sort JSON?
When Preserve Array Order is checked (the default), the order of items in arrays is left unchanged — only object keys are sorted. When unchecked, arrays containing only primitive values (strings, numbers) will also be sorted alphabetically/numerically.
Can I sort in Z-A (descending) order?
Yes. Use the Sort Direction dropdown to switch between A-Z (ascending, default) and Z-A (descending) ordering for all sorted keys.
What indent options are available?
You can choose 2 spaces, 4 spaces, or a tab character for indentation. The default is 2 spaces, which is the most common convention. Your choice applies to the formatted output.
Can I download the sorted JSON?
Yes. After sorting, click the Download button to save the result as a .json file directly to your device.
