Format GitLab CI YAML Online — .gitlab-ci.yml Beautifier
Format .gitlab-ci.yml with 2-space indent. Comments are not preserved on js-yaml round-trip.
Developer notes
Pretty-prints .gitlab-ci.yml with 2-space indent. Auto-format on paste/upload/sample; manual edits use the Format button (⌘↵). Comments may be dropped by the YAML round-trip (silent). Pair with validate-gitlab-ci for structural checks.
When teams pick this route
Clean up hand-edited .gitlab-ci.yml before merge. Align indentation across copied job templates. Format a snippet when the IDE YAML plugin is unavailable. Quick normalize before validate-gitlab-ci structural checks.

GitLab CI formatter FAQ
YAML layout only
Are comments preserved?
No. js-yaml dump drops comments. Keep a backup if annotations matter.
Does this call GitLab CI Lint API?
No — formatting is fully local. Use validate-gitlab-ci for structural checks, or GitLab’s CI Lint for runner-aware validation.
What about include: remote?
Remote includes are not fetched. The formatter only rewrites the YAML you paste.
