Parameters

0

Unique keys

Base URL

-

Query length

0

Rebuilt URL

Query string only

Values are decoded for reading and re-encoded on the way out, so you can see what hello%20world really means. Repeated keys such as tag=one&tag=two are kept in order rather than collapsed, which matters for anything that accepts a list.

What Is Query String Parser?

The Query String Parser takes a full URL or a raw parameter string and lists every key and value in an editable table. Change a value, decode or re-encode a single field, add or remove rows, and copy the rebuilt URL back out.

Who Uses the Query String Parser?

Developers and QA engineers use it to inspect a long URL without squinting at escaped characters, to build a parameterised link for a test case, and to spot the difference between an encoded space (%20) and a plus sign. Marketing and analytics staff use it to rewrite campaign URLs.

How to Use the Query String Parser

  1. Paste a URL or a bare parameter string.
  2. Edit, decode, or reorder the fields in the table.
  3. Copy the rebuilt URL, or the bare parameter string.
