Common use cases

Clean up data

Standardize names, addresses or product titles in spreadsheets and CSV exports.

Prepare code identifiers

Convert human‑written labels into camelCase, PascalCase or snake_case for variable names.

Fix accidental Caps Lock

Recover a paragraph typed entirely in capital letters by switching to Sentence case.

Polish headlines

Apply Title Case to headlines and titles for consistent style.

Worked example: Screaming CSV headers → Title Case labels

A charity CRM export used headers like `FIRST_NAME,GIFT_AID_ELIGIBLE`. For a volunteer-facing mail merge they needed `First Name` and `Gift Aid Eligible`. They pasted the header row, chose a readable title-case variant, then spot-checked that `UK` had not become `Uk` — they put the country code back by hand.

Later they used camelCase to turn `pickup-window` into `pickupWindow` for a tiny script. That is a different button; running title case on code identifiers would have inserted spaces and broken everything.

Limitations

Title case is a style choice (APA vs Chicago vs ‘capitalize every word’). Brand names (`iPhone`, `eBay`) will be wrong unless you fix them.
Unicode and non-English casing (Turkish dotted/dotless i) may not follow locale rules.
Code case (camel, snake, kebab) is mechanical. It will not infer word boundaries in `HTTPSRedirect` perfectly.
This does not translate language.

When not to use Text Case Converter

Do not bulk-title-case a legal party name list; courts care about registered spelling.
Do not run case conversion on checksums, Base64, or passwords.
If you need true sentence case with grammar, write it; a converter cannot know proper nouns.

Frequently asked questions

How do I convert text to title case online?

Paste your text into our Text Case Converter and copy the Title Case result. The first letter of each word is capitalised and the rest is lowercased.

How does the camel case converter work?

Paste your text and copy the camelCase result. Spaces, hyphens, underscores and punctuation are removed, the first letter is lowercased and each following word starts with a capital, so "user profile image", "USER PROFILE IMAGE" and "user_profile_image" all become "userProfileImage". PascalCase, snake_case and kebab-case results appear alongside it.

What text cases are supported?

We support UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE.

Is there a character limit for the text case converter?

Yes: up to 100,000 characters at once, enough for long documents. Longer text is rejected with a warning, so split very large files into parts.

Your privacy matters

Text Case Converter is designed to run in your web browser. File and text tools process bytes in memory on your device rather than uploading them to a ToolsGuru converter API. Network requests you still see are the page itself, analytics, and ads — not a copy of your document sitting in our logs. How we process files, and how to check.
