Language-aware formatting

JavaScript, HTML and CSS use js-beautify; SQL uses a dialect-aware formatter; JSON and YAML are parsed and serialized; XML is validated and safely indented.

⚠️

Formatting is not linting

A beautifier improves layout. It does not enforce your project’s semantic rules, find all bugs or replace ESLint, Stylelint, HTML validation, schema validation or test suites.

🔐

Local processing

Code and uploaded files are processed in your browser. The formatter does not send source content to ZeeSharp’s server.

Choose the right formatter settings

Match indentation and wrapping to the project’s established conventions. Automated project tools such as Prettier, ESLint, sql-formatter or editor settings should remain the source of truth for shared repositories.

How reliable is automatic language detection?

Detection uses content patterns and file extensions where available, but ambiguous fragments can be classified incorrectly. Select the language manually whenever the result looks wrong.

Are comments preserved?

JavaScript, HTML, CSS and SQL formatters normally retain comments. JSON has no comments. YAML is parsed and serialized, so YAML comments, anchors and original quote styles are not preserved.

Can beautification change behavior?

Ordinary formatter output should preserve behavior, but parser/serializer paths can normalize values or source-level details. Signed content, YAML with comments/tags, XML mixed content and embedded template languages require special care.

Does this replace Prettier?

No. This is useful for one-off inspection and cleanup. Repository formatting should use a pinned, automated formatter configuration so every contributor and CI system produces identical output.
