Developer Tools Inspect structured input clearly

Query String Parser

Query String Parser is built for inspection work. Use it when you need to review query string online, understand how the input is structured, or verify details before the next step in your workflow.

Tool interface

What this tool does

Query String Parser helps you turn a query string into readable key/value pairs in the browser so campaign links, redirect parameters, and API query strings are easier to inspect and debug.

Related next steps include Query String Builder, URL Parser, and the Build query strings for redirects page if you want to keep working on the same task from a different angle.

When to use it

Use it when you need a clear read on the source before moving on. Pages like this are useful for QA, debugging, audits, launch checks, and any workflow where a quick inspection prevents mistakes later.

If the result points to a related follow-up task, continue with Query String Builder. For the wider workflow around this type of check, open Build query strings for redirects next.

How to use it

Paste or type your input, review the result, and copy or export it once it matches what you need.

  1. Paste the source input or load the example if you want to see the expected format first.
  2. Review the output, preview, or validation result carefully.
  3. Copy, download, or pass the result into the next workflow only after you confirm it matches what you need.

Example

This example shows the kind of input and output the tool is designed to handle in a typical browser workflow.

Example input

?utm_source=newsletter&lang=en&sort=latest

Example output

{
  "utm_source": "newsletter",
  "lang": "en",
  "sort": "latest"
}

Common use cases

Inspecting source details

Use it to read the important parts of a value, file, or response before you trust it in the next step.

Catching issues before publish or handoff

A quick check here can surface mismatches, missing details, or invalid input before it affects a page, file, or integration.

Supporting QA and debugging

These inspection tools are useful during launch checks, review work, imports, and troubleshooting.

Moving to the next relevant step

If the result points to another task, continue with Query String Builder.
