All interactive tools run entirely in your browser. Your data never leaves your device.

How It Works

Paste INI content and choose a mode: Format adds consistent spacing around = signs and blank lines between sections; Minify strips comments, blank lines, and extra whitespace; Validate checks for syntax errors like empty section names or invalid lines.

Features

  • 3 modes: format (pretty-print), minify (compact), validate (error check)
  • Full INI parsing: sections, key-value pairs, comments (; and #), quoted values, inline comments
  • Statistics: section count, key count, comment count, blank line count
  • Error reporting: line-level validation errors for invalid syntax
  • 5 examples: basic config, git config, PHP.ini, desktop entry, editorconfig
  • Apply button: apply formatted/minified output back to input
  • Copy to clipboard: one-click copy of output
  • Private: runs entirely in the browser — no data transmitted

Use Cases

  • Cleaning up messy configuration files
  • Minifying INI files for deployment
  • Validating configuration syntax before deploying
  • Converting between compact and readable INI formats
  • Checking .editorconfig and php.ini files
