All ToolsSort all keys in a JSON object alphabetically. Load sample
Sort all JSON object keys alphabetically with one click. Choose ascending (A→Z) or descending (Z→A) order. Enable recursive mode to sort nested objects at every level. Useful for normalizing JSON for diffs, making config files easier to scan, standardizing API response shapes, and reducing noise in code reviews when key order keeps changing.
JavaScript objects don't guarantee key order, but many serializers and humans prefer alphabetical order for readability. Sorting keys makes it easier to find properties, produces cleaner diffs in version control (fewer false changes when keys move around), and helps when comparing two JSON structures side by side.
No. Key order is not significant in JSON — any order is valid. Sorting keys doesn't change the data, only the presentation order. The sorted output is always valid JSON with identical values.
