BundleSafe

BundleSafe is an editor for Java .properties resource bundles. It shows one key across its locale files and previews each file before applying the edit.

What it preserves

• comments, ordering, separators, and untouched escape spelling;
• UTF-8 and ISO-8859-1 files, including BOM and native-to-ASCII forms;
• CRLF, LF, mixed line endings, and missing trailing newlines;
• duplicate-key semantics used by Java.

BundleSafe works locally and does not collect usage data or send file contents over the network.

Notes on .properties files

• Editing a value without rewriting the file
• Why line endings and escape spelling change
• UTF-8, BOMs, and \uXXXX escapes
