About JSON Parser

JSON parsing is the process of taking a raw JSON string and converting it into a structured, readable data format. This is especially useful when working with API responses, log files, or configuration data where JSON may arrive as a single minified line or, even more commonly, as a double-encoded string — a JSON value wrapped in extra escape characters like {\"key\": \"value\"}.

Our JSON Parser runs entirely in your browser using the native JSON.parse API. It automatically detects and recursively unwraps double-encoded (stringified) JSON, so you never have to manually strip escape characters. The tool displays type information, key counts, nesting depth, and the number of parse passes required — giving you instant insight into the structure of your data without any server-side processing.

How to Use

01

Paste or Upload JSON

Paste your raw or double-encoded JSON string into the input pane, or upload a .json file.

02

Click Parse

Hit the "Parse" button. The tool recursively parses the input until it reaches a structured result.

03

Review the Output

View the pretty-printed result, check type and depth info in the stats bar, and copy the parsed output.

Frequently Asked Questions

What is a JSON Parser? expand_more
A JSON parser takes a raw JSON string and converts it into a structured JavaScript value (object, array, string, number, boolean, or null). It validates the syntax and makes the data readable and navigable.
How does it handle double-encoded JSON? expand_more
When JSON is stringified multiple times (e.g., an API wraps a JSON object inside a string), our parser detects this and recursively calls JSON.parse until the result is no longer a string. The stats bar shows how many parse passes were needed.
Is my data safe? expand_more
Yes. All parsing happens locally in your browser using the native JSON.parse function. No data is sent to any server, so your JSON stays completely private.
What types of input are supported? expand_more
The parser handles objects, arrays, strings, numbers, booleans, null, and any combination of these — including edge cases like escaped/double-encoded strings and raw primitives like "42" or "true".
