Make messy computer code neat and easy to read.

About this Tool

Sometimes, computer code called JSON looks like one giant, confusing block of text. When APIs return data or when developers minify configuration files for production, all the spaces and line breaks are removed to save bandwidth.

While this is great for computer systems, it makes it incredibly difficult for humans to read, understand, or troubleshoot the data. Our free JSON Formatter cleans it up instantly!

It organizes the code neatly so you can easily read it and find mistakes. The tool automatically adds proper indentation, color-codes the syntax to differentiate keys from values, and flags any syntax errors so you can fix them immediately.

Because this tool runs entirely in your web browser, your sensitive data is never uploaded to any external server, ensuring complete privacy.
