Frequently Asked Questions
How does Sentence case detect where a new sentence starts? ↓
Sentence case detects standard sentence terminators including periods (.), exclamation marks (!), question marks (?), and line breaks. It capitalizes the first letter following each terminator while lowercasing other letters, and keeps the standalone personal pronoun "I" and contractions like "I'm" capitalized.
What is the difference between camelCase, snake_case, and kebab-case? ↓
These are identifier naming conventions commonly used in programming:
• camelCase: The first word starts with a lowercase letter, and all subsequent words start with a capital letter without spaces (e.g., userProfileImage).
• snake_case: All words are written in lowercase and separated by underscores (e.g., user_profile_image).
• kebab-case: All words are written in lowercase and separated by hyphens (e.g., user-profile-image).
Does this tool support multiple lines of text? ↓
Yes. All conversion styles fully respect multi-line text and paragraphs. Identifier formats (camelCase, snake_case, kebab-case) convert each line independently, making it effortless to convert lists of database columns, JSON keys, or variable lists in one quick operation.
Is there any limit to the amount of text I can convert? ↓
Because processing takes place directly inside your device's browser memory, there are no artificial server limits. You can convert short phrases or large multi-thousand-word essays smoothly and without restrictions.
