Frequently Asked Questions

Why sort JSON keys?

Sorted keys make JSON diffs cleaner, improve readability in config files, and ensure consistent ordering across environments. It also helps with version control — no unnecessary diffs from random key order changes.

Are arrays affected?

No. Array element order is preserved — only object keys are sorted. Objects inside arrays will have their keys sorted if recursive mode is enabled.
