JSON Formatter & Validator
Beautify, minify and validate JSON — all in your browser.
Working with JSON
JSON (JavaScript Object Notation) is the most common format for exchanging data between apps and APIs. This tool does three things: beautify re-indents JSON so it’s readable, minify strips whitespace so it’s as small as possible, and validate checks the syntax and points to the first error. Everything happens in your browser, so even sensitive payloads stay private. Pair it with our Base64 tool when APIs hand you encoded data.
JSON FAQ
What does a JSON formatter do?
It re-indents JSON so it is easy to read (beautify), removes whitespace to shrink it (minify), and checks that the syntax is valid.
Is my JSON uploaded anywhere?
No. Everything is processed in your browser and your data never leaves your device.
