About Smart Case Converter
Sometimes you want to change the case of only part of a text, for example converting the string values inside quotation marks in code while leaving keywords and identifiers alone. A regular case converter would change everything.
This tool converts case only inside quotes, which makes refactoring string literals, labels, or keys in code and data files quicker and safer. It runs in your browser and does not modify anything outside the quoted segments.
Common use cases
- Changing the case of string literals in source code.
- Renaming quoted keys or labels in configuration files.
- Normalizing quoted values in a data file.
- Batch-editing text without touching surrounding syntax.
Frequently asked questions
- What counts as inside quotes?
- Text between matching quote characters. Review the result if your text contains nested or escaped quotes.
- How is this different from the Text Case Converter?
- Text Case Converter transforms the whole input. Smart Case changes only the quoted parts.
- Can I undo a conversion?
- Keep your original text; the tool does not track changes, so copy the input before converting.
