Overview

Formatters beautify code for review; minifiers remove whitespace for production bundles. Utilnivo groups language-specific tools so you can pick the grammar you are editing.

Minified output should be tested before deploy — aggressive minification can break templates that relied on significant whitespace. Compare tools (XML Compare) help review config drift between environments.

CSV Viewer and Markdown Previewer add readable views for data and docs without leaving the browser.

How to choose

  • Web stack → HTML, CSS, or JavaScript Formatter.
  • Config/data → XML, YAML, or SQL Formatter.
  • Production bundle → HTML, CSS, or JS Minifier.
  • Docs preview → Markdown Previewer.

Frequently asked questions

Do formatters fix syntax errors?

They may fail on invalid input. Use validators first when parsing fails.

Is minification reversible?

Beautifiers can re-indent but cannot restore lost comments.

Which formatter for mixed files?

Pick the language-specific tool. Do not paste HTML into the CSS formatter.
