How to Format JSON

A step-by-step process to format JSON for review, debugging, and safer team handoff.

Quick answer: To format JSON safely: validate syntax, choose stable indentation, sort keys only when useful for diffing, and keep one canonical format in reviews.

Formatting workflow

Start from raw JSON input and validate syntax before any beautification.

Once valid, apply consistent indentation and line breaks to reduce review noise.

  • Validate before formatting.
  • Use one indentation style per project.
  • Keep formatting rules consistent in PRs.

Formatting for diffs

Formatting is most useful when it improves change visibility. If key order is unstable, optional key sorting can reduce noise.

For semantic review, diff normalized JSON rather than mixed raw payloads.

  • Prefer pretty JSON in code review.
  • Use key sort mode when order is irrelevant.
  • Separate formatting changes from data changes when possible.

FAQ

Should I always sort JSON keys?

Only when key order has no business meaning and sorting improves readability in diffs.

What indentation is best for JSON?

Two spaces is a common default, but team consistency matters more than the exact number.

Can formatting change data meaning?

Pure formatting should not, but parsing and re-serialization can expose invalid original data.
