When to use this tool
Read JSON embedded in a percent-encoded URL parameter. Decode the URL representation before formatting the recovered JSON.

Use “Try example” to load this public sample and its settings, then run it.
Input
%7B%22name%22%3A%22Serialize%22%2C%22count%22%3A2%7D
Result
{
"name": "Serialize",
"count": 2
}How the result is produced
Conventions and limitations
Some systems encode values more than once. Apply only the required number of decoding steps, and check whether plus signs represent spaces for your source.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
