JSON Key Sorter
Sort object keys recursively for readable diffs while retaining array order and JSON values.
Developers comparing API fixtures and normalizing JSON configuration diffs.
Free to use. Your inputs are processed in this browser and are not included in usage analytics.
How to use json key sorter
- Paste JSON containing object keys you want to order.
- Choose indentation and sort keys at every nesting level.
- Copy the result to make key-order-only diffs easier to compare.
What to know about the result
- Processing stays in your browser. Pasted JSON is never executed.
- Use quoted strings for integers beyond ±9,007,199,254,740,991. Inputs are limited to 200,000 characters and 64 nesting levels.
- Keys are sorted by Unicode code-unit order, including numeric-looking keys. Array item order is preserved.
