How to use the JSON Array Sorter
1. Paste a JSON array (of strings, numbers, or objects) into the left panel.
2. For arrays of objects, enter the key name to sort by (e.g. "name" or "age").
3. Choose ascending (A→Z / 0→9) or descending order and copy the sorted result.
What is it?
Sorting JSON arrays is a frequent data processing task — ordering a list of users by name, sorting API results by date, or ranking items by score. JavaScript's built-in sort() mutates arrays and has quirks with mixed types; this tool performs a safe, non-mutating sort and returns clean JSON.
For arrays of objects, the optional Sort Key field lets you sort by any nested property. String comparisons use locale-aware ordering (localeCompare), while numbers are sorted numerically. The original array is never modified.
Example
[{"name":"Bob","age":25},{"name":"Alice","age":30},{"name":"Carol","age":22}][
{"name":"Carol","age":22},
{"name":"Bob","age":25},
{"name":"Alice","age":30}
]Benefits
Sort API response arrays by any key without writing code
Order results by price, date, name, score, or any field instantly — no array.sort() with a custom comparator required.
Prepare sorted data for display components that expect a specific order
Charts, tables, and ranked lists often render correctly only when data is pre-sorted — do it here before passing to your component.
Sort log entries and event arrays chronologically
Order JSON arrays by timestamp to trace event sequences and correlate events across a timeline.
Find the top and bottom records in a dataset instantly
Sort descending to surface the highest values, or ascending to find the lowest — without SQL or code.
Frequently asked questions
Can I sort an array of objects by nested keys?
The current implementation supports one level of key depth (e.g., 'name' not 'address.city'). For deeply nested key sorting, you would need a programmatic approach.
How are mixed-type arrays sorted?
If the array contains mixed types (strings and numbers), comparisons may produce unexpected results. For best results, sort arrays of a single type.
Does this sort in-place?
No — the original array is not modified. A new sorted copy is returned. The original input remains unchanged in the left panel.
