Query String Parser
Parse URLs and query strings to JSON, or build query strings from JSON. Live param table, duplicate keys, encode options.
5 params
| # | Key | Value |
|---|---|---|
| 1 | q | hello world |
| 2 | lang | en |
| 3 | tag | dev |
| 4 | tag | tools |
| 5 | utm_source |
Base path: https://easy24.tools/search · Hash: #results
Accepts full URLs, raw ?key=value strings, or JSON for building. Repeated keys become arrays when parsing (toggle off to keep last value only).
How it works
Paste URL or JSON
Parse mode accepts a full URL or query string like ?q=hello&lang=en. Build mode accepts a JSON object; array values repeat the key.
Review parameters
In Parse mode, a live table lists decoded keys and values. Duplicate keys become JSON arrays unless you disable that option. Base path and hash are detected from full URLs.
Copy or build URL
Copy JSON or the built query string. In Build mode, set an optional base URL to get a complete link. Swap flips input and output direction.
Why parse query strings?
Query strings carry tracking tags, filters, and API parameters. Query String Parser is part of Easy24’s developer toolbox. Your input stays in this tab for normal use; Easy24 does not upload that content to process it. This tool has no daily free-plan cap; use it as often as you need. Typical flow: Paste a full URL, ?a=1&b=2, or JSON. Parse shows a key/value table and JSON output. Build converts JSON to an encoded query or full URL. Related tools and reverse conversions appear on the page when a follow-up step is common.
Why use this tool
- URL and query string → JSON
- JSON → encoded query string
- Live parameter table
- Duplicate keys as arrays
- Optional full URL builder
- Unlimited use on the free plan
Questions
What input formats are supported?
Full URLs (https://…?a=1), raw query strings (?a=1 or a=1&b=2), and JSON objects for building query strings.
How are duplicate keys handled?
By default repeated keys become a JSON array. Turn off Duplicates as arrays to keep only the last value.
Can I build a full URL from JSON?
Yes. Switch to Build, paste JSON, and enter a base URL. The output combines base + encoded query string.
Are values URL-decoded?
Yes. The parameter table and JSON output show decoded values (+ as space).

When to use Query String Parser
People reach for Query String Parser when a quick job should not require installing desktop software or creating an account. Parse URLs and query strings to JSON, or build query strings from JSON. Developer utilities remove friction from small tasks: formatting, snippets, colors, loaders, and other front-end helpers. Compared with installing a desktop suite only for query string parser, a dedicated page keeps the interface small and the intent obvious. Quota cookies may still track anonymous daily free-plan uses. That is different from receiving your file bytes or pasted text. This page has no daily free-plan cap, so you can run it as often as you need. If a free-plan limit applies, the workspace shows remaining uses before you commit a download, so you are not surprised after a long wait.
