Introduction
Case Converter changes the letter case of a draft without rewriting its words. It is useful when text arrives in ALL CAPS, inconsistent casing or a format that does not match a title, sentence or catalogue field.
Use cases
- Turn an all-caps supplier title into a readable draft.
- Standardise headings before adding them to a sheet or catalogue.
- Compare sentence case, title case, uppercase and lowercase versions.
Steps
- Paste the exact text you want to reformat.
- Choose the case style that matches the destination.
- Read the converted text once because brand names and abbreviations may need manual correction.
Example
Practical example
Example: convert “WIRELESS MOUSE WITH USB RECEIVER” to “Wireless Mouse With Usb Receiver”, then manually restore the abbreviation as “USB” before publishing.
Limitations
- Automatic title case cannot know every brand or proper-noun exception.
- Changing letter case does not correct spelling, facts or grammar.
- Keep a copy of the original when formatting matters to an existing record.
Privacy and file processing
