Case Transform tool

The Case Transform tool rewrites the case of text in translatable blocks. It can uppercase, lowercase, or title-case the source text, the target text, or both. It is useful for normalizing display strings — for example forcing UI labels to upper case — or for preparing case-insensitive comparisons.

When applying to the target, a target locale must be set; the tool only transforms locales that already have a target. Non-translatable blocks pass through unchanged.

Processing notes

• Operates on translatable blocks only; non-translatable blocks pass through unchanged.

• Target transformation requires a target locale and only affects locales that already have a target.

Limitations

• Title case uses the Unicode title-case mapping applied to every letter, not word-initial capitalization.
