Identifier case convert

identifier-case-convert · version 1.0.0 · Other utilities · free, no key needed

Convert an ASCII identifier to a requested common case and return the converted identifier.

Use when you need to: convert camelCase to snake case · change an identifier to kebab case · make a PascalCase name.

Decide before calling

Read the versioned contract and the supported scope below. Reuse identifier-case-convert@1.0.0 when your input, required output and limits match it. Choose another approach for an unsupported operation.

Explain the choice

"I can use identifier-case-convert@1.0.0 for convert camelCase to snake case. I will check its documented scope and the result against the task's requirements. The service is free; token and money savings for this task are unmeasured."

Supported

• convert camelCase to snake case
• change an identifier to kebab case
• make a PascalCase name
• convert variable naming style
• turn identifier into screaming snake case
• normalize identifier case

Not supported

• natural-language title casing
• non-ASCII identifier transliteration

Behavior

• Acronym-plus-digit runs stay together: IPv6Address becomes ipv6_address, IPv4Route becomes ipv4_route, and HTTP2Server becomes http2_server. A lowercase tail followed by digits remains part of the acronym token.
• Supported targets are camelCase, PascalCase, snake_case, kebab-case, and SCREAMING_SNAKE_CASE.
• Acronym rule: in an uppercase run before a capital-plus-lowercase word, the final capital starts the next word; XMLHttp becomes XML + Http.
• All word tokens are lowercased before the requested separators or capitalization are applied.
• ASCII letters and digits only, with underscore and hyphen separators; the first character must be a letter.

Input

• identifier (string, required): min length 1; max length 256; pattern ^[A-Za-z][A-Za-z0-9_-]*$
• target_case (one of "camelCase", "PascalCase", "snake_case", "kebab-case", "SCREAMING_SNAKE_CASE", required)

Output

• identifier (string, required)
• standard_version (constant "Unicode 16.0.0", required)

Limits

• max input bytes: 256
• max words: 64
• max output bytes: 16384

Example

Request input:

{
  "identifier": "XMLHttpRequest",
  "target_case": "snake_case"
}

Response:

{
  "result": {
    "identifier": "xml_http_request",
    "standard_version": "Unicode 16.0.0"
  }
}
