How to use Text Case Converter
Paste your text and select a case button. The result appears below the original, which remains available for comparison. Copy the result or download it as a plain text file. Edit the source to try a different version.
A practical example
Uppercase changes “Hola, España” to “HOLA, ESPAÑA”. Sentence case changes “HOLA MUNDO. NUEVO DÍA.” to “Hola mundo. Nuevo día.”
What to check before using the result
Title case capitalizes individual words; it does not apply a Spanish editorial style guide. Sentence case starts by lowercasing the text, so brand names, acronyms and proper nouns need a final review. No spelling or grammar correction is performed.
Frequently asked question
Will this preserve names and abbreviations?
The original input is preserved, but the converted result follows the selected mechanical rule. Review names such as Madrid and acronyms such as URL before publication.
