What it does

Parse any URL's query string into key/value pairs — including repeated keys, array-style key[] keys, and bracket-notation key[a][b]. Shows raw and decoded values so you can catch double-encoding bugs.

For the full URL breakdown use URL parser. For UTM parameters specifically, UTM parser. To encode single values, URL encoder/decoder.

How to use it

  1. Paste a URL or a raw query string.
  2. Read the parsed key/value rows.
  3. Toggle array-style parsing (brackets) if needed.
  4. Copy individual pairs or the whole table as JSON.
