String Converter
Convert between string formats (camelCase, snake_case, etc.)
About the String Converter
Naming things consistently is one of those small chores that eats real time. The String Converter takes a word or phrase and rewrites it into any of ten naming conventions — camelCase, snake_case, kebab-case, PascalCase, SCREAMING_SNAKE_CASE, train-case, dot.case, space case, lowercase, or UPPERCASE — and converts directly between them.
It is built for the moments developers hit constantly: turning a database column like first_name into the firstName your API layer expects, converting a React component name into the kebab-case slug its file should use, or reformatting a list of constants into SCREAMING_SNAKE_CASE before pasting them into a config. Technical writers and translators reach for it too, when a glossary needs to move between human-readable "space case" and machine-friendly identifiers.
Because you pick both a "From" and a "To" format, the tool understands the structure of what you paste rather than blindly lower-casing it — so MyVariableName splits correctly into the words "my", "variable", "name" before it is reassembled.
How to Use the String Converter
- Paste or type your text into the "Input String" box.
- Choose the format your text is currently in from the "From" dropdown (for example, PascalCase).
- Choose the format you want from the "To" dropdown (for example, snake_case).
- Read the converted result instantly — it updates as you type or change either dropdown.
- Use the swap button between the two dropdowns to reverse the direction without re-selecting, then click Copy to send the result to your clipboard.
Why Use ToolForge’s String Converter
- Conversion runs entirely in your browser in JavaScript — nothing you paste is uploaded, so internal variable names and unreleased identifiers stay on your machine.
- It handles all ten common conventions in one place and converts between any pair, rather than only "to camelCase" like many single-purpose converters.
- The dedicated "From" selector means the tool parses word boundaries correctly instead of guessing, so compound names round-trip cleanly.
- Results are live and there is no length limit in the code, so you can convert a single token or a whole pasted block at once.
Frequently Asked Questions
What is the difference between camelCase and PascalCase?
Both join words without separators, but camelCase leaves the first word lowercase (myVariableName) while PascalCase capitalizes every word including the first (MyVariableName). camelCase is conventional for variables and functions in many languages; PascalCase is common for class and component names.
Why does my converted text look wrong?
Most often the "From" format does not match the actual format of your input. The tool relies on that setting to find word boundaries — if you pick camelCase but your text is already snake_case, it cannot split the words correctly. Set "From" to match your real input and the result will be accurate.
Is my text sent to a server?
No. The conversion happens locally in your browser using plain JavaScript. Nothing is transmitted or stored, which makes it safe for proprietary code and internal naming.
Can I convert more than one line at a time?
The tool converts the full contents of the input box as a single string. For converting many separate identifiers in bulk, paste them one per line and convert, or use a regex tool for line-by-line transformation.
