Clean, debug, and validate your JSON data instantly. Beautify messy code or minify it for production with one click.
Working with JSON (JavaScript Object Notation) is a daily task for modern developers, but raw data from APIs or databases is often minified and impossible to read. Our JSON Formatter And Validator is a powerful, browser-based utility designed to help you beautify JSON online, identify syntax errors, and prepare data for production. Whether you are a backend engineer debugging a REST API or a data analyst cleaning up nested objects, this tool provides the clarity you need.
Minified JSON is great for reducing bandwidth, but it's a nightmare for human troubleshooting. A JSON beautifier adds consistent indentation and line breaks, allowing you to visualize the hierarchy of your data. Our tool supports custom indentation levels (2 spaces or 4 spaces), making it easy to match your project's coding standards. By using a JSON viewer, you can quickly spot missing keys, incorrect data types, or deeply nested structures that might be causing bugs in your application.
Syntax errors are the most common cause of broken code. Our JSON validator doesn't just tell you if your code is wrong; it tells you why.
If our validator flags your code as "Invalid," check for these common mistakes:
{ has a matching } and every [ has a matching ].Just as our Meta Tag Generator helps you perfect your SEO code, this JSON Formatter ensures your data structures are flawless before they hit your server.
JSON has become the universal language of the web. From NoSQL databases like MongoDB to configuration files like package.json, having a reliable JSON viewer and editor is essential. Our tool helps you transition between development (beautified) and production (minified) states seamlessly. If you're managing large documentation sets, you might also find our Merge PDF Online tool useful for combining technical specs alongside your formatted code samples.
The JSON Formatter And Validator is a lightweight yet robust solution for anyone working with structured data. By combining a beautifier, minifier, and syntax checker into one interface, we've created a workflow that saves time and reduces frustration. Clean up your code, fix those pesky syntax errors, and get back to building amazing things.
Our tool can handle several megabytes of JSON data comfortably. However, extremely large files (50MB+) may cause your browser to slow down. For standard API responses and config files, it works instantly.
Currently, this tool focuses on formatting, minifying, and validating JSON. It ensures your JSON is syntactically correct and readable. We are working on XML and CSV conversion features for future updates.
This error usually means there is a character where it shouldn't be. Common causes include using single quotes instead of double quotes, missing a comma between key-value pairs, or having an extra comma at the end of a list.
