ToolbitCase Converter for Identifiers
Rename a batch of identifiers to match the convention of the codebase you are moving into. Paste a list, pick a target case, and copy the converted names back out.
What the Case Converter does
- camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and Title Case.
- Converts whole lists line by line, not just a single word.
- Splits acronyms and digits the way linters expect.
- Round-trips cleanly between any two conventions.
How to use it
- Paste the identifiers, one per line.
- Choose the target naming convention.
- Copy the converted list into your editor.
Why it runs locally
Toolbit has no backend. The Case Converter is implemented with standard browser APIs, so your input is processed in the tab and never uploaded, logged, or retained. That is what makes it safe to paste real data into — and it is also why the tool keeps working with the network disconnected, once you have installed Toolbit as an app.
Frequently asked questions
- Can it convert a whole file of names at once?
- Yes. Each line is converted independently, so you can paste an entire column of field names.
- How are acronyms handled?
- Runs of capitals such as HTTPResponse are split at the boundary so you get httpResponse rather than hTTPResponse.
- Is my text uploaded?
- Local transformations process input in your browser. HTTP and WebSocket tools send user-initiated requests. Optional product analytics is off by default, excludes tool input and output, and stays off when your browser signals Do Not Track or Global Privacy Control.
