When people reach for this tool
Fix the capitalisation of text from somewhere else
Notes, transcripts and exports arrive in all shapes; one click makes them consistent.
Convert between naming styles
Snake case, kebab case, camel case and the rest are all one conversion apart.
Get title and sentence case right every time
Capitalising every word looks wrong for most styles and is tedious to do properly by hand.
Practical tips
- Title case capitalises every word including small ones. For most English copy, sentence case reads better and takes less effort.
- Run the transform once and read the result — automatic capitalisation occasionally misreads an acronym or a proper noun.
What you get
- Letter case: upper, lower, title, sentence, inverse
- Code style: camelCase, PascalCase, snake_case, kebab-case, CONSTANT
- Whitespace cleanup that collapses extra spaces
- Live word and character count
Text Transformer — FAQ
What is sentence case?
It capitalizes the first letter of each sentence (after . ! ?) and lowercases the rest.
What does “collapse spaces” do?
It replaces runs of whitespace with a single space, preserving line breaks.
Which case should I use for headings?
It depends on the style. Sentence case reads more naturally and is easier to keep consistent, while title case is a common convention for headings in formal documents.
Does it handle accents and non-Latin scripts?
The conversions work on the characters present, so accented letters are preserved. Scripts without letter case, such as Arabic or Chinese, are unaffected.
