Use this parser to convert a string in the named grammar into a structured value while making accepted syntax and failures explicit.

Feet and inches

Required string input.

Parse feet and inches notation into total inches. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Total inches (in)

The resulting total inches returned as a number.

• Parsing rules depend on locale, radix, encoding, escaping, duplicate fields, whitespace, overflow, rounding, time zone, units, and ambiguity policy. Successful parsing does not validate business meaning or make untrusted input safe.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Reject trailing or ambiguous content, preserve the original input, schema-validate the parsed value, and test malformed, boundary, and adversarial cases.

• Cache-Control Header Parser

  Tokenize an RFC 9111 Cache-Control header into a record of directives; valueless flags become true and numeric values become numbers.

• Currency Parser
