Common Questions About Text Formatting & Case Toolkit
What is the difference between camelCase and snake_case?
camelCase capitalizes the first letter of each subsequent word without spaces (e.g., 'myVariableName'), while snake_case uses underscores to separate lowercase words (e.g., 'my_variable_name'). Both are standard programming conventions.
Is there a character limit for formatting?
There is no hard limit imposed by the tool. However, formatting blocks exceeding 5 million characters may cause temporary browser lag depending on your device's RAM.
