What is a Sentence Case Converter?
A text capitalization tool is an intelligent utility designed to enforce standard grammatical capitalization across written content. Programmatically, the algorithm scans a string for terminal punctuation marks—specifically periods, exclamation points, and question marks. Once it detects a terminal mark, it targets the very next alphabetical character and shifts its encoding value to uppercase, while strictly forcing every subsequent letter to lowercase until the next terminal punctuation is found. This automated scanning prevents you from having to manually proofread and edit capitalization errors line by line.

Frequently Asked Questions
No, it does not use natural language processing to identify proper nouns. The script applies a strict rule: the first letter after a terminal punctuation mark becomes capitalized, and all subsequent letters become lowercase. You will need to manually capitalize specific names, brands, or cities after running the conversion.
This utility only capitalizes the single letter at the absolute beginning of a phrase, mirroring standard grammatical writing. A title modifier, on the other hand, capitalizes the first letter of almost every individual word, which is typically used for book titles or headlines.
