How to use Java Properties Formatter

Paste your Java .properties file, and the tool normalizes every line to key=value form, groups comments, and can sort keys alphabetically.

Frequently asked questions

What separators are supported?

Both '=' and ':' are recognized as key-value separators. The output normalizes every entry to the conventional key=value form.

Can it sort the keys?

Yes. Enable the sort option to reorder entries alphabetically by key, which makes large property files far easier to scan and diff.

Are comments kept?

Comment lines starting with # or ! are collected and placed at the top so they aren't lost during formatting.
