Choose a case style.
Review and copy the result.
Six predictable rules
Choose the right case style
Character case and identifier formats serve different jobs. Texite keeps line breaks where the selected format allows them and never edits the original until you choose Replace original.
UPPERCASE and lowercase are useful when the surrounding spacing and punctuation should remain exactly where they are. Title Case applies a general headline rule and keeps common short words lowercase in the middle of a title. Sentence case lowers most letters before capitalizing the start of each detected sentence, so it needs a quick review when the source contains abbreviations or deliberately styled names.
camelCase and snake_case are designed for labels, field names, and code-like identifiers. They split text at spaces, punctuation, underscores, hyphens, and existing case boundaries. Each line is converted separately, which prevents an entire multi-line list from becoming one identifier. Numbers stay in place, and Texite does not invent a prefix when an identifier begins with a number.
Automatic conversion cannot know that a particular word is a product name, person, place, or acronym. Keep the original visible, scan the preview for names such as iPhone or eBay, and copy only after the result matches the style you need.
Reading and publishing
UPPERCASE and lowercase preserve spacing. Title Case and Sentence case apply consistent general rules, but names still need review.
Code and structured labels
camelCase joins tokens without separators. snake_case converts tokens to lowercase and joins them with underscores.
Safe preview
Changing the selected style only updates the result. Your original remains editable and available until you deliberately replace it.

Common questions
Frequently asked questions
What case styles are available?
Texite supports UPPERCASE, lowercase, Title Case, Sentence case, camelCase, and snake_case. Each style is applied locally as you edit.
Will Title Case preserve brand names?
Not reliably. Texite preserves short all-capital abbreviations, but automatic rules cannot identify every brand, acronym, or proper noun. Review names before publishing.
What is the difference between camelCase and snake_case?
camelCase removes separators and capitalizes each word after the first, as in firstExample. snake_case uses lowercase words joined by underscores, as in first_example.
Does the converter upload my text?
No. Conversion happens in your browser, and Texite does not send or save your original or converted text.
Can I undo a conversion?
Switching case styles never changes your original. If you choose Replace original or Clear text, Texite keeps one in-memory snapshot so you can undo the latest action.
