Short answer

How can I get a sorted list of languages from an Accept-Language header?

Your AI uses the parse_accept_language tool to turn a raw string into a structured list. It sorts the languages by their weight so you know exactly which ones the user prefers. You get a clean object ready for your localization logic.

The results.

Where your data lands.

The AI transforms raw text into structured data you can actually use in your code.

STRUCTURED

Clean language lists

The tool converts a single string into a list of language tags. You get a predictable format instead of a messy header.

ORDERED

Weighted priority

The AI respects the q-values in the header. It sorts the languages from most preferred to least preferred automatically.

READY

i18n integration

The output is formatted for immediate use in your internationalization logic. You can pass this directly to your routing or content delivery systems.

HUMAN

Manual overrides

If the header is missing or malformed, you decide the fallback language. The AI provides the data, but you set the final policy.

The workflow

What your AI does when the header arrives.

The AI acts as a translator between raw network data and your application logic.

  1. Receive raw string

    Your AI takes the raw Accept-Language string from your request or log file.

    parse_accept_language

  2. Deconstruct weights

    The tool identifies each language tag and its associated quality value.

    parse_accept_language

  3. Sort preferences

    The AI organizes the languages based on the user's specific priority levels.

  4. Output structured data

    The final result is a clean, sorted list that your application can read easily.

  • Parse this header for me: 'en-US,en;q=0.9,fr;q=0.8'

  • Take the Accept-Language string from my production logs and give me a sorted list.

  • Convert this header into a JSON object: 'da, en-gb;q=0.8, en;q=0.7'

  • Look at the language preferences in this request header and tell me the top three choices.

FAQ

How this task behaves.

  • 01

    Does the AI change the original header?

    No. The AI only reads the header and provides a new, structured version of that data.

  • 02

    Can the AI automatically pick a language for my website?

    No. The AI provides the sorted list of preferences, but you must write the logic that selects the final language based on that list.

  • 03

    What happens if the header is empty?

    The tool will return an empty list or a null value, leaving you to apply your default fallback language.

  • 04

    Does it handle complex q-values?

    Yes, the tool is designed to parse the weightings to ensure the order is correct.

  • 05

    Can I use this to modify HTTP requests?

    No. This tool is for parsing and extracting information from existing strings, not for intercepting or altering live network traffic.
