The Ultimate JSON Developer Tool
Whether you are debugging an API response or configuring a server, reading raw JSON data is painful. The NoLoginTool JSON Formatter helps you organize messy code into a readable, structured format.
Main Features
- JSON Beautifier: Turn one-line blobs into clean, indented code (2 spaces, 4 spaces, or tabs).
- JSON Minifier: Remove all whitespace to reduce file size for production environments.
- Tree View: Navigate complex, nested JSON objects with collapsible nodes.
- Validator: Instantly find syntax errors. We pinpoint the exact line and column number of the issue.
Privacy First (Client-Side)
Many online formatters send your data to a backend server. We do not. Our tool runs entirely in your browser using JavaScript. Your API keys, configuration files, and private data never leave your computer.
Data Conversion
Need to move data between systems? Use our built-in converters to transform JSON into XML, YAML, or CSV (Excel compatible) with a single click.
