JSON Formatter & Validator
Description
JSON (JavaScript Object Notation) is the language of the web APIs, but raw JSON is often messy, minified, and hard to read. The Adiminium JSON Formatter & Validator is a developer's best friend. It takes your chaotic data strings and transforms them into a clean, indented, and readable structure. More than just a "Pretty Printer," it also validates the syntax, highlighting errors like missing commas or unmatched braces, so you can debug API responses in seconds. All processing happens locally in your browser, keeping your sensitive data secure.
What It Does
Formats (pretty-prints), validates, and minifies JSON data.
How To Use
- Paste: Input your raw JSON string into the left panel.
- Format: Click "Format / Beautify" to produce a clean, 2-space indented version in the right panel.
- Validate: If there are errors, they will appear in the status bar with details.
- Minify: Use "Minify" to strip whitespace for production use.
Who It Is For
Backend developers, frontend engineers, data analysts, and API consumers.
Freqently Asked Questions
Is my data private?
Absolutely. We do not send your JSON to any server. Validation happens locally using JavaScript's
native JSON.parse().
What does "Minify" do?
It removes all unnecessary spaces, newlines, and indentation to reduce the file size, which is ideal for transmitting data over the network.
Can it fix errors?
It can detect them, but it cannot automatically fix them (e.g., guessing where a missing bracket belongs) as that might corrupt your data.
