Case Converter (camelCase/snake_case)
Case Converter: converts supplied text to lower, upper, title, camel, or snake mode. Title, camel, and snake split runs of Unicode letters and numbers at other characters; lower and upper transform the supplied text directly.
About this case converter (camelcase/snake_case)
Case Converter (camelCase/snake_case) — browser-based utility.
How this tool works
Accepts two text fields: input text and a mode. Lower and upper call the corresponding JavaScript string transform on the supplied text. Title, camel, and snake trim the input, split it at runs outside Unicode letters and numbers, then normalize each resulting word.
- Read the supplied text and the trimmed case-mode field.
- For lower or upper, transform the supplied text directly.
- For title, camel, or snake, split the trimmed text at runs outside Unicode letters and numbers.
- Normalize each token for the selected mode and return the resulting string, or an explicit mode error.
Worked example
Scenario: Convert a phrase with title mode.
Sample input:
Processing: Split word runs and uppercase each first code unit.
Illustrative output:
Limits and verification
Only lower, upper, title, camel, and snake modes are implemented; an empty mode defaults to lower and any other mode is rejected. Title/camel/snake are token transforms, not locale-aware casing, acronym preservation, grapheme segmentation, Pascal/kebab conversion, identifier parsing, or a reversible transformation.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
Which case modes does Case Converter provide?+
Enter text in the first field and choose lower, upper, title, camel, or snake in the second. Leaving the mode blank uses lower.
How do title, camel, and snake treat separators?+
Those modes trim the input, split it wherever one or more characters are not Unicode letters or numbers, then normalize each resulting word. For example, `CZOA browser tools` in title becomes `Czoa Browser Tools`.
What are the conversion limits?+
Lower and upper apply JavaScript string casing directly. The word-based modes do not preserve acronyms, apply locale-specific casing, segment grapheme clusters, parse identifiers, or provide Pascal or kebab modes; conversion is not reversible.
Is text sent to a conversion server?+
No. The tool converts the text supplied in this browser and shows the resulting string. It does not read project files, rename files, or upload the entered text for conversion.
