Frequently Asked Questions
How do I convert text to title case online?
To convert text to title case online, paste your text into the converter, select "Title Case" from the conversion options, and click convert. The tool will capitalize the first letter of significant words while leaving articles, prepositions, and conjunctions in lowercase unless they start or end the text.
What is the difference between sentence case and title case?
Sentence case capitalizes only the first word of each sentence, while title case capitalizes most words including nouns, verbs, adjectives, and adverbs. In title case, short words like articles (a, an, the), prepositions (of, in, to), and conjunctions (and, but, or) are typically not capitalized unless they appear first or last.
Can I convert camel case to normal text?
Yes, the case converter can transform camel case text back to normal spacing. Simply paste camel case text (like "camelCaseText") and select the appropriate conversion option to add spaces and proper formatting.
Is there a free case converter tool without download?
Yes, our case converter is completely free with no download required. Visit https://fireuptool.com/tools/text/case-converter to access all features instantly through your web browser without any software installation.
How to change case in Excel without formulas?
While Excel has functions like UPPER(), LOWER(), and PROPER(), using an online case converter eliminates the need for formulas. Simply copy your Excel text, paste it into the converter, and paste the result back into Excel.
What browser extensions convert text case?
Browser extensions like our case converter add-on for Chrome provide instant text transformation. These extensions allow you to right-click any text and convert it to your desired case format without leaving the webpage.
Can I convert multiple case types at once?
The case converter processes one conversion type at a time for the best results. However, you can quickly perform multiple conversions by running different selections sequentially on the same text.
How to convert alternating case back to normal?
Alternating case text (like "AlTeRnAtInG cAsE") can be converted to normal case by selecting "Lower Case" or "Sentence Case" depending on your desired formatting. The tool will standardize the capitalization.
Is there a case converter for Google Docs?
While Google Docs doesn't have a built-in case converter, you can use our online tool by copying text from your document, converting it, and pasting the result back. Some browser extensions also provide direct integration with Google Docs.
What formats does a case converter support?

Yes, our case converter is mobile-friendly and works on smartphones and tablets. The responsive design adapts to different screen sizes, allowing you to convert text on any device with a web browser.
How to maintain punctuation when converting case?
The case converter preserves punctuation marks during conversion. Periods, commas, question marks, exclamation points, and other punctuation remain in their original positions while only the letter case changes.
Is there a batch case converter for files?
Our online case converter allows you to paste and convert multiple text segments quickly. For larger batch processing needs, you may need to process sections separately or use specialized bulk conversion tools.
What is snake case and how to convert it?
Snake case replaces spaces with underscores (e.g., "hello world" becomes "hello_world"). It's commonly used in programming for variable names. Our case converter includes snake case as a conversion option.
Can I save custom case conversion rules?
