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

URL

Absolute URL to parse.

Split an absolute hierarchical URL into protocol, host, port, path, query, and fragment components. Bracketed IPv6 hosts and user-info prefixes are supported. 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]

Protocol

Protocol including the trailing colon.

Host

Host name or bracketed IPv6 address, excluding user info and port.

Port

Port as a string, empty when absent.

Path

Path beginning with a slash.

Query

Query string without the leading question mark.

Fragment

Fragment identifier without the leading hash.

• 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.

• Query String Parser

  Parse a URL query string into an object of decoded keys and string values (repeated keys keep the last value).

• 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

  Parse a currency amount using an explicit currency code and number format.
