• Value Alignment — Align all equals signs to the same column within each section for maximum readability. Transforms messy key=value pairs into clean, aligned configuration.
• Spacing Options — Choose between spaced (key = value) and compact (key=value) formatting around equals signs.
• Section & Key Sorting — Optionally sort sections alphabetically and/or sort keys within each section. Great for standardizing configuration files across environments.
• Comment Normalization — Preserve original comment style, or normalize all comments to # or ; prefix for consistency.
• Structure View — Tree/outline view showing sections as top-level nodes with key-value pairs indented underneath. Includes section count, key count, and comment count per section.
• Validation Warnings — Detects duplicate keys within sections, keys outside any section (global keys), empty sections, and unparseable lines.
• Additional Options — Blank lines between sections, trim trailing whitespace, remove inline comments, remove duplicate keys (keep last occurrence).
• Exportieren — Copy formatted output, download as .ini file, or download as .cfg file.

INI File Format

INI files use a simple structure: [section] headers group related settings, key=value pairs store configuration values, and # or ; prefixes mark comments. This format is used by php.ini, my.cnf (MySQL), Windows configuration files, Git config (.gitconfig), Python’s configparser, and many application settings files.
